Library and information science

Library and information science(s) or studies (LIS) is an interdisciplinary field of study that deals generally with organization, access, collection, and protection/regulation of information, whether in physical (e.g. art, legal proceedings, etc.) or digital forms.

In spite of various trends to merge the two fields, some consider the two original disciplines, library science and information science, to be separate. However, it is common today to use the terms synonymously or to drop the term "library" and to speak about information departments or I-schools. There have also been attempts to revive the concept of documentation and to speak of Library, information and documentation studies (or science).

Relations between library science, information science and LIS

Tefko Saracevic (1992, p. 13) argued that library science and information science are separate fields:

The common ground between library science and information science, which is a strong one, is in the sharing of their social role and in their general concern with the problems of effective utilization of graphic records. But there are also very significant differences in several critical respects, among them in: (1) selection of problems addressed and in the way they were defined; (2) theoretical questions asked and frameworks established;(3) the nature and degree of experimentation and empirical development and the resulting practical knowledge/competencies derived; (4) tools and approaches used; and (5) the nature and strength of interdisciplinary relations established and the dependence of the progress and evolution of interdisciplinary approaches. All of these differences warrant the conclusion that librarianship and information science are two different fields in a strong interdisciplinary relation, rather than one and the same field, or one being a special case of the other.

Another indication of the different uses of the two terms are the indexing in UMI's Dissertations Abstracts. In Dissertations Abstracts Online in November 2011 were 4888 dissertations indexed with the descriptor LIBRARY SCIENCE and 9053 with the descriptor INFORMATION SCIENCE. For the year 2009 the numbers were 104 LIBRARY SCIENCE and 514 INFORMATION SCIENCE. 891 dissertations were indexed with both terms (36 in 2009).

It should be considered that information science grew out of documentation science and therefore has a tradition for considering scientific and scholarly communication, bibliographic databases, subject knowledge and terminology etc. Library science, on the other hand has mostly concentrated on libraries and their internal processes and best practices. It is also relevant to consider that information science used to be done by scientists, while librarianship has been split between public libraries and scholarly research libraries. Library schools have mainly educated librarians for public libraries and not shown much interest in scientific communication and documentation. When information scientists from 1964 entered library schools, they brought with them competencies in relation to information retrieval in subject databases, including concepts such as recall and precision, boolean search techniques, query formulation and related issues. Subject bibliographic databases and citation indexes provided a major step forward in information dissemination - and also in the curriculum at library schools.

Julian Warner (2010) suggests that the information and computer science tradition in information retrieval may broadly be characterized as query transformation, with the query articulated verbally by the user in advance of searching and then transformed by a system into a set of records. From librarianship and indexing, on the other hand, has been an implicit stress on selection power enabling the user to make relevant selections.

Library science

Library science (often termed library studies, bibliothecography, and library economy) is an interdisciplinary or multidisciplinary field that applies the practices, perspectives, and tools of management, information technology, education, and other areas to libraries; the collection, organization, preservation, and dissemination of information resources; and the political economy of information. Martin Schrettinger, a Bavarian librarian, coined the discipline within his work (1808–1828) Versuch eines vollständigen Lehrbuchs der Bibliothek-Wissenschaft oder Anleitung zur vollkommenen Geschäftsführung eines Bibliothekars. Rather than classifying information based on nature-oriented elements, as was previously done in his Bavarian library, Schrettinger organized books in alphabetical order. The first American school for library science was founded by Melvil Dewey at Columbia University in 1887.

Historically, library science has also included archival science. This includes how information resources are organized to serve the needs of selected user groups, how people interact with classification systems and technology, how information is acquired, evaluated and applied by people in and outside libraries as well as cross-culturally, how people are trained and educated for careers in libraries, the ethics that guide library service and organization, the legal status of libraries and information resources, and the applied science of computer technology used in documentation and records management.

There is no generally agreed-upon distinction between the terms library science and librarianship. To a certain extent, they are interchangeable perhaps differing most significantly in connotation. The term library and information studies (alternatively library and information science), abbreviated as LIS, is most often used; most librarians consider it as only a terminological variation, intended to emphasize the scientific and technical foundations of the subject and its relationship with information science. LIS should not be confused with information theory, the mathematical study of the concept of information. Library philosophy has been contrasted with library science as the study of the aims and justifications of librarianship as opposed to the development and refinement of techniques.

Difficulties defining LIS

"The question, 'What is library and information science?' does not elicit responses of the same internal conceptual coherence as similar inquiries as to the nature of other fields, e.g., 'What is chemistry?', 'What is economics?', 'What is medicine?' Each of those fields, though broad in scope, has clear ties to basic concerns of their field. [...] Neither LIS theory nor practice is perceived to be monolithic nor unified by a common literature or set of professional skills. Occasionally, LIS scholars (many of whom do not self-identify as members of an interreading LIS community, or prefer names other than LIS), attempt, but are unable, to find core concepts in common. Some believe that computing and internetworking concepts and skills underlie virtually every important aspect of LIS, indeed see LIS as a sub-field of computer science! [Footnote III.1] Others claim that LIS is principally a social science accompanied by practical skills such as ethnography and interviewing. Historically, traditions of public service, bibliography, documentalism, and information science have viewed their mission, their philosophical toolsets, and their domain of research differently. Still others deny the existence of a greater metropolitan LIS, viewing LIS instead as a loosely organized collection of specialized interests often unified by nothing more than their shared (and fought-over) use of the descriptor information. Indeed, claims occasionally arise to the effect that the field even has no theory of its own." (Konrad, 2007, p. 652–653).

A multidisciplinary, interdisciplinary or monodisciplinary field?

The Swedish researcher Emin Tengström (1993) described cross-disciplinary research as a process, not a state or structure. He differentiates three levels of ambition regarding cross-disciplinary research:

• The "Pluridisciplinary" or "multidisciplinarity" level
• The genuine cross-disciplinary level: "interdisciplinarity"
• The discipline-forming level "transdisciplinarity"

What is described here is a view of social fields as dynamic and changing. Library and information science is viewed as a field that started as a multidisciplinary field based on literature, psychology, sociology, management, computer science etc., which is developing towards an academic discipline in its own right. However, the following quote seems to indicate that LIS is actually developing in the opposite direction:

Chua & Yang (2008) studied papers published in Journal of the American Society for Information Science and Technology in the period 1988–1997 and found, among other things: "Top authors have grown in diversity from those being affiliated predominantly with library/information-related departments to include those from information systems management, information technology, business, and the humanities. Amid heterogeneous clusters of collaboration among top authors, strongly connected crossdisciplinary coauthor pairs have become more prevalent. Correspondingly, the distribution of top keywords’ occurrences that leans heavily on core information science has shifted towards other subdisciplines such as information technology and sociobehavioral science."

A more recent study revealed that 31% of the papers published in 31 LIS journals from 2007 through 2012 were by authors in academic departments of library and information science (i.e., those offering degree programs accredited by the American Library Association or similar professional organizations in other countries). Faculty in departments of computer science (10%), management (10%), communication (3%), the other social sciences (9%), and the other natural sciences (7%) were also represented. Nearly one-quarter of the papers in the 31 journals were by practicing librarians, and 6% were by others in non-academic (e.g., corporate) positions.

As a field with its own body of interrelated concepts, techniques, journals, and professional associations, LIS is clearly a discipline. But by the nature of its subject matter and methods LIS is just as clearly an interdiscipline, drawing on many adjacent fields (see below).

A fragmented adhocracy

Richard Whitley (1984, 2000) classified scientific fields according to their intellectual and social organization and described management studies as a 'fragmented adhocracy', a field with a low level of coordination around a diffuse set of goals and a non-specialized terminology; but with strong connections to the practice in the business sector. Åström (2006) applied this conception to the description of LIS.

Scattering of the literature

Meho & Spurgin (2005) found that in a list of 2,625 items published between 1982 and 2002 by 68 faculty members of 18 schools of library and information science, only 10 databases provided significant coverage of the LIS literature. Results also show that restricting the data sources to one, two, or even three databases leads to inaccurate rankings and erroneous conclusions. Because no database provides comprehensive coverage of the LIS literature, researchers must rely on a wide range of disciplinary and multidisciplinary databases for ranking and other research purposes. Even when the nine most comprehensive databases in LIS was searched and combined, 27.0% (or 710 of 2,635) of the publications remain not found.

The study confirms earlier research that LIS literature is highly scattered and is not limited to standard LIS databases. What was not known or verified before, however, is that a significant amount of this literature is indexed in the interdisciplinary or multidisciplinary databases of Inside Conferences and INSPEC. Other interdisciplinary databases, such as America: History and Life, were also found to be very useful and complementary to traditional LIS databases, particularly in the areas of archives and library history. (Meho & Spurgin, 2005, p.1329).

The unique concern of library and information science

"Concern for people becoming informed is not unique to LIS, and thus is insufficient to differentiate LIS from other fields. LIS are a part of a larger enterprise." (Konrad, 2007, p. 655).

"The unique concern of LIS is recognized as: Statement of the core concern of LIS: Humans becoming informed (constructing meaning) via intermediation between inquirers and instrumented records. No other field has this as its concern. " (Konrad, 2007, p. 660)

"Note that the promiscuous term information does not appear in the above statement circumscribing the field's central concerns: The detrimental effects of the ambiguity this term provokes are discussed above (Part III). Furner [Furner 2004, 427] has shown that discourse in the field is improved where specific terms are utilized in place of the i-word for specific senses of that term." (Konrad, 2007, p. 661).

Michael Buckland wrote: "Educational programs in library, information and documentation are concerned with what people know, are not limited to technology, and require wide-ranging expertise. They differ fundamentally and importantly from computer science programs and from the information systems programs found in business schools."

Bawden and Robinson argue that while Information Science has overlaps with numerous other disciplines with interest in studying communication, it is unique in that it is concerned with all aspects of the communication chain. For example, Computer Science may be interested in the indexing and retrieval, sociology with user studies, and publishing (business) with dissemination, whereas information science is interested in the study of all of these individual areas and the interactions between them.

The organization of information and information resources is one of the fundamental aspects of LIS. and is an example of both LIS's uniqueness and its multidisciplinary origins. Some of the main tools used by LIS toward this end to provide access to the digital resources of modern times (particularly theory relating to indexing and classification) originated in 19th century to assist humanity's effort to make its intellectual output accessible by recording, identifying, and providing bibliographic control of printed knowledge. The origin for some of these tools were even earlier. For example, in the 17th century, during the 'golden age of libraries', publishers and sellers seeking to take advantage of the burgeoning book trade developed descriptive catalogs of their wares for distribution – a practice was adopted and further extrapolated by many libraries of the time to cover areas like philosophy, sciences, linguistics, medicine, etc. In this way, a business concern of publishers – keeping track of and advertising inventory – was developed into a system for organizing and preserving information by the library.

The development of Metadata is another area that exemplifies the aim of LIS to be something more than an mishmash of several disciplines – that uniqueness Bawden and Robinson describe. Pre-Internet classification systems and cataloging systems were mainly concerned with two objectives: 1. to provide rich bibliographic descriptions and relations between information objects and 2. to facilitate sharing of this bibliographic information across library boundaries. The development of the Internet and the information explosion that followed found many communities needing mechanisms for the description, authentication and management of their information. These communities developed taxonomies and controlled vocabularies to describe their knowledge as well as unique information architectures to communicate these classifications and libraries found themselves as liaison or translator between these metadata systems. Of course the concerns of cataloging in the Internet era have gone beyond simple bibliographic descriptions. The need for descriptive information about the ownership and copyright of a digital product – a publishing concern – and description for the different formats and accessibility features of a resource – a sociological concern – show the continued development and cross discipline necessity of resource description.

In the 21st century, the usage of open data, open source and open protocols like OAI-PMH has allowed thousands of libraries and institutions to collaborate on the production of global metadata services previously offered only by increasingly expensive commercial proprietary products. Examples include BASE and Unpaywall, which automates the search of an academic paper across thousands of repositories by libraries and research institutions.

Christopher M. Owusu-Ansah argued that, Many African universities have employed distance education to expand access to education and digital libraries can ensure seamless access to information for distance learners.

LIS theories

Julian Warner (2010, p. 4–5) suggests that

Two paradigms, the cognitive and the physical, have been distinguished in information retrieval research, but they share the assumption of the value of delivering relevant records (Ellis 1984, 19; Belkin and Vickery 1985, 114). For the purpose of discussion here, they can be considered a single heterogeneous paradigm, linked but not united by this common assumption. The value placed on query transformation is dissonant with common practice, where users may prefer to explore an area and may value fully informed exploration. Some dissenting research discussions have been more congruent with practice, advocating explorative capability—the ability to explore and make discriminations between representations of objects—as the fundamental design principle for information retrieval systems.

Among other approaches, Evidence Based Library and Information Practice should also be mentioned.

Theory and practice

Many practicing librarians do not contribute to LIS scholarship but focus on daily operations within their own libraries or library systems. Other practicing librarians, particularly in academic libraries, do perform original scholarly LIS research and contribute to the academic end of the field.

Whether or not individual professional librarians contribute to scholarly research and publication, many are involved with and contribute to the advancement of the profession and of library science through local, state, regional, national, and international library or information organizations.

Library science is very closely related to issues of knowledge organization; however, the latter is a broader term that covers how knowledge is represented and stored (computer science/linguistics), how it might be automatically processed (artificial intelligence), and how it is organized outside the library in global systems such as the internet. In addition, library science typically refers to a specific community engaged in managing holdings as they are found in university and government libraries, while knowledge organization, in general, refers to this and also to other communities (such as publishers) and other systems (such as the Internet). The library system is thus one socio-technical structure for knowledge organization.

The terms information organization and knowledge organization are often used synonymously. The fundamentals of their study (particularly theory relating to indexing and classification) and many of the main tools used by the disciplines in modern times to provide access to digital resources (abstracting, metadata, resource description, systematic and alphabetic subject description, and terminology) originated in the 19th century and were developed, in part, to assist in making humanity's intellectual output accessible by recording, identifying, and providing bibliographic control of printed knowledge.

Information has been published that analyses the relations between the philosophy of information (PI), library and information science (LIS), and social epistemology (SE).

Ethics

Practicing library professionals and members of the American Library Association recognize and abide by the ALA Code of Ethics. According to the American Library Association, "In a political system grounded in an informed citizenry, we are members of a profession explicitly committed to intellectual freedom and freedom of access to information. We have a special obligation to ensure the free flow of information and ideas to present and future generations." The ALA Code of Ethics was adopted in the winter of 1939, and updated on June 29, 2021.

Education and training

Main article: Education for librarianship

Academic courses in library science include collection management, information systems and technology, research methods, information literacy, cataloging and classification, preservation, reference, statistics and management. Library science is constantly evolving, incorporating new topics like database management, information architecture and information management, among others. With the mounting acceptance of Wikipedia as a valued and reliable reference source, many libraries, museums, and archives have introduced the role of Wikipedian in residence. As a result, some universities are including coursework relating to Wikipedia and Knowledge Management in their MLIS programs.

Most schools in the US only offer a master's degree in library science or an MLIS and do not offer an undergraduate degree in the subject. About fifty schools have this graduate program, and seven are still being ranked. Many have online programs, which makes attending more convenient if the college is not in a student's immediate vicinity. According to US News' online journal, the University of Illinois is at the top of the list of best MLIS programs provided by universities. Second is the University of North Carolina and third is the University of Washington.

Most professional library jobs require a professional post-baccalaureate degree in library science or one of its equivalent terms. In the United States and Canada the certification usually comes from a master's degree granted by an ALA-accredited institution, so even non-scholarly librarians have an original academic background. In the United Kingdom, however, there have been moves to broaden the entry requirements to professional library posts, such that qualifications in, or experience of, a number of other disciplines have become more acceptable. In Australia, a number of institutions offer degrees accepted by the ALIA (Australian Library and Information Association). Global standards of accreditation or certification in librarianship have yet to be developed.

In academic regalia in the United States, the color for library science is lemon.

The Master of Library Science (MLIS) is the master's degree that is required for most professional librarian positions in the United States and Canada. The MLIS is a relatively recent degree; an older and still common degree designation for librarians to acquire is the Master of Library Science (MLS), or Master of Science in Library Science (MSLS) degree. According to the American Library Association (ALA), "The master’s degree in library and information studies is frequently referred to as the MLS; however, ALA-accredited degrees have various names such as Master of Arts, Master of Librarianship, Master of Library and Information Studies, or Master of Science. The degree name is determined by the program. The [ALA] Committee for Accreditation evaluates programs based on their adherence to the Standards for Accreditation of Master's Programs in Library and Information Studies, not based on the name of the degree

Employment outlook and opportunities

According to U.S. News & World Report, library and information science ranked as one of the "Best Careers of 2008". The median annual salary for 2020 was reported by the U.S. Bureau of Labor Statistics as $60,820 in the United States. Additional salary breakdowns available by metropolitan area show that the San Jose-Sunnyvale-Santa Clara metropolitan area has the highest average salary at $86,380. In September 2021, the BLS projected growth for the field "to grow 9 percent from 2020 to 2030", which is "about as fast as the average for all occupations". The 2010-2011 Occupational Outlook Handbook states, "Workers in this occupation tend to be older than workers in the rest of the economy. As a result, there may be more workers retiring from this occupation than other occupations. However, relatively large numbers of graduates from MLS programs may cause competition in some areas and for some jobs."

Types of librarianship

Public

The study of librarianship for public libraries covers issues such as cataloging; collection development for a diverse community; information literacy; readers' advisory; community standards; public services-focused librarianship; serving a diverse community of adults, children, and teens; intellectual freedom; censorship; and legal and budgeting issues. The public library as a commons or public sphere based on the work of Jürgen Habermas has become a central metaphor in the 21st century.

Most people are familiar with municipal public libraries, but there are, in fact, four different types of public libraries: association libraries, municipal public libraries, school district libraries, and special district public libraries. It is important to be able to distinguish among the four. Each receives its funding through different sources, each is established by a different set of voters, and not all are subject to municipal civil service governance.

School

The study of school librarianship covers library services for children in primary through secondary school. In some regions, the local government may have stricter standards for the education and certification of school librarians (who are often considered a special case of teacher), than for other librarians, and the educational program will include those local criteria. School librarianship may also include issues of intellectual freedom, pedagogy, information literacy, and how to build a cooperative curriculum with the teaching staff.

Academic

The study of academic librarianship covers library services for colleges and universities. Issues of special importance to the field may include copyright; technology, digital libraries, and digital repositories; academic freedom; open access to scholarly works; as well as specialized knowledge of subject areas important to the institution and the relevant reference works. Librarians often divide focus individually as liaisons on particular schools within a college or university.

Some academic librarians are considered faculty, and hold similar academic ranks to those of professors, while others are not. In either case, the minimal qualification is a Master of Arts in Library Studies or a Master of Arts in Library Science. Some academic libraries may only require a master's degree in a specific academic field or a related field, such as educational technology.

Archival

The study of archives includes the training of archivists, librarians specially trained to maintain and build archives of records intended for historical preservation. Special issues include physical preservation, conservation, and restoration of materials and mass deacidification; specialist catalogs; solo work; access; and appraisal. Many archivists are also trained historians specializing in the period covered by the archive.

The archival mission includes three major goals: To identify papers and records with enduring value, preserve the identified papers, and make the papers available to others.

There are significant differences between libraries and archives, including differences in collections, records creation, item acquisition, and preferred behavior in the institution. The major difference in collections is that library collections typically comprise published items (books, magazines, etc.), while archival collections are usually unpublished works (letters, diaries, etc.) In managing their collections, libraries will categorize items individually, but archival items never stand alone. An archival record gains meaning and importance from its relationship to the entire collection; therefore archival items are usually received by the archive in a group or batch. Library collections are created by many individuals, as each author and illustrator create their own publication; in contrast, an archive usually collects the records of one person, family, institution, or organization, so the archival items will have fewer sources of authors.

Another difference between a library and an archive is that library materials are created explicitly by authors or others who are working intentionally. They choose to write and publish a book, for example, and that occurs. Archival materials are not created intentionally. Instead, the items in an archive are what remains after a business, institution, or person conducts their normal business practices. The collection of letters, documents, receipts, ledger books, etc. was created with the intention to perform daily tasks, they were not created in order to populate a future archive.

As for item acquisition, libraries receive items individually, but archival items will usually become part of the archive's collection as a cohesive group.

Behavior in an archive differs from behavior in a library, as well. In most libraries, patrons are allowed and encouraged to browse the stacks, because the books are openly available to the public. Archival items almost never circulate, and someone interested in viewing documents must request them of the archivist and may only view them in a closed reading room. Those who wish to visit an archive will usually begin with an entrance interview. This is an opportunity for the archivist to register the researcher, confirm their identity, and determine their research needs. This is also the opportune time for the archivist to review reading room rules, which vary but typically include policies on privacy, photocopying, the use of finding aids, and restrictions on food, drinks, and other activities or items that could damage the archival materials.

Special

Special libraries are libraries established to meet the highly specialized requirements of professional or business groups. A library is special depending on whether it covers a specialized collection, a special subject, or a particular group of users, or even the type of parent organization. A library can be special if it only serves a particular group of users such as lawyers, doctors, nurses, etc. These libraries are called professional libraries and special librarians include almost any other form of librarianship, including those who serve in medical libraries (and hospitals or medical schools), corporations, news agencies, government organizations, or other special collections. The issues at these libraries are specific to their industries but may include solo work, corporate financing, specialized collection development, and extensive self-promotion to potential patrons. Special librarians have their own professional organization, the Special Libraries Association (SLA).

National Center for Atmospheric Research (NCAR) is considered a special library. Its mission is to support, preserve, make accessible, and collaborate in the scholarly research and educational outreach activities of UCAR/NCAR.

Another is the Federal Bureau of Investigation Library. According to its website, "The FBI Library supports the FBI in its statutory mission to uphold the law through the investigation of violations of federal criminal law; to protect the United States from foreign intelligence and terrorist activities; and to provide leadership and law enforcement assistance to federal, state, local, and international agencies.

A further example would be the classified CIA Library. It is a resource to employees of the Central Intelligence Agency, containing over 125,000 written materials, subscribes to around 1,700 periodicals, and had collections in three areas: Historical Intelligence, Circulating, and Reference. In February 1997, three librarians working at the institution spoke to Information Outlook, a publication of the SLA, revealing that the library had been created in 1947, the importance of the library in disseminating information to employees, even with a small staff, and how the library organizes its materials. In May 2021, an unnamed gay librarian, for the institution, was shown in a recruitment video for the agency.

Preservation

Main article: Preservation (library and archival science)

Preservation librarians most often work in academic libraries. Their focus is on the management of preservation activities that seek to maintain access to content within books, manuscripts, archival materials, and other library resources. Examples of activities managed by preservation librarians include binding, conservation, digital and analog reformatting, digital preservation, and environmental monitoring.

History

The Library of Alexandria, an early library.

17th century

Portrait of Gabriel Naudé, author of Advis pour dresser une bibliothèque (1627), later translated into English in 1661

The earliest text on "library operations", Advice on Establishing a Library was published in 1627 by French librarian and scholar Gabriel Naudé. Naudé wrote prolifically, producing works on many subjects including politics, religion, history, and the supernatural. He put into practice all the ideas put forth in Advice when given the opportunity to build and maintain the library of Cardinal Jules Mazarin.

19th century

Martin Schrettinger wrote the second textbook (the first in Germany) on the subject from 1808 to 1829.

Thomas Jefferson, whose library at Monticello consisted of thousands of books, devised a classification system inspired by the Baconian method, which grouped books more or less by subject rather than alphabetically, as it was previously done.

The Jefferson collection provided the start of what became the Library of Congress.

The first American school of librarianship opened at Columbia University under the leadership of Melvil Dewey, noted for his 1876 decimal classification, on January 5, 1887, as the School of Library Economy. The term library economy was common in the U.S. until 1942, with the term, library science, predominant through much of the 20th century. Key events are described in "History of American Library Science: Its Origins and Early Development."

20th century

Later, the term was used in the title of S. R. Ranganathan's The Five Laws of Library Science, published in 1931, and in the title of Lee Pierce Butler's 1933 book, An Introduction to Library Science (University of Chicago Press).

S. R. Ranganathan conceived the five laws of library science and the development of the first major analytical-synthetic classification system, the colon classification.

In the United States, Lee Pierce Butler's new approach advocated research using quantitative methods and ideas in the social sciences with the aim of using librarianship to address society's information needs. He was one of the first faculty at the University of Chicago Graduate Library School, which changed the structure and focus of education for librarianship in the twentieth century. This research agenda went against the more procedure-based approach of the "library economy," which was mostly confined to practical problems in the administration of libraries.

William Stetson Merrill's A Code for Classifiers, released in several editions from 1914 to 1939, is an example of a more pragmatic approach, where arguments stemming from in-depth knowledge about each field of study are employed to recommend a system of classification. While Ranganathan's approach was philosophical, it was also tied more to the day-to-day business of running a library. A reworking of Ranganathan's laws was published in 1995 which removes the constant references to books. Michael Gorman's Our Enduring Values: Librarianship in the 21st Century features the eight principles necessary by library professionals and incorporates knowledge and information in all their forms, allowing for digital information to be considered.

In the English-speaking world the term "library science" seems to have been used for the first time in India in the 1916 book Punjab Library Primer, written by Asa Don Dickinson and published by the University of Punjab, Lahore, Pakistan. This university was the first in Asia to begin teaching "library science". The Punjab Library Primer was the first textbook on library science published in English anywhere in the world. The first textbook in the United States was the Manual of Library Economy by James Duff Brown, published in 1903. In 1923, C. C. Williamson, who was appointed by the Carnegie Corporation, published an assessment of library science education entitled "The Williamson Report," which designated that universities should provide library science training. This report had a significant impact on library science training and education. Library research and practical work, in the area of information science, have remained largely distinct both in training and in research interests.

From Library Science to LIS

By the late 1960s, mainly due to the meteoric rise of human computing power and the new academic disciplines formed therefrom, academic institutions began to add the term "information science" to their names. The first school to do this was at the University of Pittsburgh in 1964. More schools followed during the 1970s and 1980s, and by the 1990s almost all library schools in the USA had added information science to their names. Although there are exceptions, similar developments have taken place in other parts of the world. In Denmark, for example, the 'Royal School of Librarianship' changed its English name to The Royal School of Library and Information Science in 1997.

21st century

The digital age has transformed how information is accessed and retrieved. "The library is now a part of a complex and dynamic educational, recreational, and informational infrastructure." Mobile devices and applications with wireless networking, high-speed computers and networks, and the computing cloud have deeply impacted and developed information science and information services. The evolution of the library sciences maintains its mission of access equity and community space, as well as the new means for information retrieval called information literacy skills. All catalogs, databases, and a growing number of books are available on the Internet. In addition, the expanding free access to open-source journals and sources such as Wikipedia has fundamentally impacted how information is accessed. Information literacy is the ability to "determine the extent of information needed, access the needed information effectively and efficiently, evaluate information and its sources critically, incorporate selected information into one’s knowledge base, use information effectively to accomplish a specific purpose, and understand the economic, legal, and social issues surrounding the use of information, and access and use information ethically and legally."

An advertisement for a full Professor in information science at the Royal School of Library and Information Science, spring 2011, provides one view of which subdisciplines are well-established: "The research and teaching/supervision must be within some (and at least one) of these well-established information science areas

• a. Knowledge organization
• b. Library studies
• c. Information architecture
• d. Information behavior
• e. Interactive information retrieval
• f. Information systems
• g. Scholarly communication
• h. Digital literacy (cf information literacy)
• i. Bibliometrics or scientometrics
• j. Interaction design and user experience"
• k. Digital library

There are other ways to identify subfields within LIS, for example bibliometric mapping and comparative studies of curricula. Bibliometric maps of LIS have been produced by, among others, Vickery & Vickery (1987, frontispiece), White & McCain (1998), Åström (2002), 2006) and Hassan-Montero & Herrero-Solana (2007). An example of a curriculum study is Kajberg & Lørring, 2005. In this publication are the following data reported (p 234): "Degree of overlap of the ten curricular themes with subject areas in the current curricula of responding LIS schools

• Information seeking and Information retrieval 100%
• Library management and promotion 96%
• Knowledge management 86%
• Knowledge organization 82%
• Information literacy and learning 76%
• Library and society in a historical perspective (Library history) 66%
• The Information society: Barriers to the free access to information 64%
• Cultural heritage and digitisation of the cultural heritage (Digital preservation) 62%
• The library in the multi-cultural information society: International and intercultural communication 42%
• Mediation of culture in a special European context 26% "

There is often an overlap between these subfields of LIS and other fields of study. Most information retrieval research, for example, belongs to computer science. Knowledge management is considered a subfield of management or organizational studies.

Library

From Wikipedia, the on-line, free encyclopedia

https://en.wikipedia.org/wiki/Library 

A modern reading room in the State and University Library, Denmark

A library is a collection of materials, books or media that are accessible for use and not just for display purposes. A library provides physical (hard copies) or digital access (soft copies) materials, and may be a physical location or a virtual space, or both. A library's collection can include printed materials and other physical resources in many formats such as DVD, CD and cassette as well as access to information, music or other content held on bibliographic databases.

A library, which may vary widely in size, may be organized for use and maintained by a public body such as a government; an institution such as a school or museum; a corporation; or a private individual. In addition to providing materials, libraries also provide the services of librarians who are trained and experts at finding, selecting, circulating and organizing information and at interpreting information needs, navigating and analyzing very large amounts of information with a variety of resources.

Library buildings often provide quiet areas for studying, as well as common areas for group study and collaboration, and may provide public facilities for access to their electronic resources; for instance: computers and access to the Internet. The library's clientele and services offered vary depending on its type: users of a public library have different needs from those of a special library or academic library, for example. Libraries may also be community hubs, where programs are delivered and people engage in lifelong learning. Modern libraries extend their services beyond the physical walls of a building by providing material accessible by electronic means, including from home via the Internet.

The services that libraries offer are variously described as library services, information services, or the combination "library and information services", although different institutions and sources define such terminology differently.

Etymology

The term library is based on the Latin word liber for 'book' or 'document', contained in Latin libraria 'collection of books' and librarium 'container for books'. Other modern languages use derivations from Ancient Greek βιβλιοθήκη (bibliothēkē), originally meaning 'book container', via Latin bibliotheca (cf. French bibliothèque or German Bibliothek).

History

Main article: History of libraries

 

The Sistine Hall of the Vatican Library

The history of libraries began with the first efforts to organize collections of documents. The first libraries consisted of archives of the earliest form of writing—the clay tablets in cuneiform script discovered in Sumer, some dating back to 2600 BC. Private or personal libraries made up of written books appeared in classical Greece in the 5th century BC. In the 6th century, at the very close of the Classical period, the great libraries of the Mediterranean world remained those of Constantinople and Alexandria.

The Fatimids (r. 909–1171) also possessed many great libraries within their domains. The historian Ibn Abi Tayyi’ describes their palace library, which probably contained the largest collection of literature on earth at the time, as a "wonder of the world". Throughout history, along with bloody massacres, the destruction of libraries has been critical for conquerors who wish to destroy every trace of the vanquished community's recorded memory. A prominent example of this can be found in the Mongol massacre of the Nizaris at Alamut in 1256 and the torching of their library, "the fame of which", boasts the conqueror Juwayni, "had spread throughout the world".

The libraries of Timbuktu were established in the fourteenth century and attracted scholars from all over the world.

Functions

Libraries may provide physical or digital access to material, and may be a physical location or a virtual space, or both. A library's collection can include books, periodicals, newspapers, manuscripts, films, maps, prints, documents, microform, CDs, cassettes, videotapes, DVDs, Blu-ray Discs, e-books, audiobooks, databases, table games, video games and other formats. Libraries range widely in size, up to millions of items.

Libraries often provide quiet areas for studying, and they also often offer common areas to facilitate group study and collaboration. Libraries often provide public facilities for access to their electronic resources and the Internet. Public and institutional collections and services may be intended for use by people who choose not to—or cannot afford to—purchase an extensive collection themselves, who need material no individual can reasonably be expected to have, or who require professional assistance with their research.

Services offered by a library are variously described as library services, information services, or the combination "library and information services", although different institutions and sources define such terminology differently. Organizations or departments are often called by one of these names.

Organization

Library shelves in Hong Kong, showing numbers of the classification scheme to help readers locate works in that section

Most libraries have materials arranged in a specified order according to a library classification system, so that items may be located quickly and collections may be browsed efficiently. Some libraries have additional galleries beyond the public ones, where reference materials are stored. These reference stacks may be open to selected members of the public. Others require patrons to submit a "stack request", which is a request for an assistant to retrieve the material from the closed stacks: see List of closed stack libraries.

Larger libraries are often divided into departments staffed by both paraprofessionals and professional librarians.

• Circulation (or Access Services) – Handles user accounts and the loaning/returning and shelving of materials.
• Collection Development – Orders materials and maintains materials budgets.
• Reference – Staffs a reference desk answering questions from users (using structured reference interviews), instructing users, and developing library programming. Reference may be further broken down by user groups or materials; common collections are children's literature, young adult literature, and genealogy materials.
• Electronic Library - Responsible for providing information to users via electronic means
• Technical Services – Works behind the scenes cataloging and processing new materials and deaccessioning weeded materials.
• Stacks Maintenance – Re-shelves materials that have been returned to the library after patron use and shelves materials that have been processed by Technical Services. Stacks Maintenance also shelf reads the material in the stacks to ensure that it is in the correct library classification order.

Basic tasks in library management include the planning of acquisitions (which materials the library should acquire, by purchase or otherwise), library classification of acquired materials, preservation of materials (especially rare and fragile archival materials such as manuscripts), the deaccessioning of materials, patron borrowing of materials, and developing and administering library computer systems. More long-term issues include the planning of the construction of new libraries or extensions to existing ones, and the development and implementation of outreach services and reading-enhancement services (such as adult literacy and children's programming). Library materials like books, magazines, periodicals, CDs, etc. are managed by Dewey Decimal Classification Theory and modified Dewey Decimal Classification Theory is more practical reliable system for library materials management.

The International Organization for Standardization (ISO) has published several standards regarding the management of libraries through its Technical Committee 46 (TC 46), which is focused on "libraries, documentation and information centers, publishing, archives, records management, museum documentation, indexing and abstracting services, and information science". The following is a partial list of some of them:

• ISO 2789:2006 Information and documentation—International library statistics
• ISO 11620:1998 Information and documentation—Library performance indicators
• ISO 11799:2003 Information and documentation—Document storage requirements for archive and library materials
• ISO 14416:2003 Information and documentation—Requirements for binding of books, periodicals, serials, and other paper documents for archive and library use—Methods and materials
• ISO/TR 20983:2003 Information and documentation—Performance indicators for electronic library services

Usage

Until the advent of digital catalogues, card catalogues were the traditional method of organizing the list of resources and their location within a large library.

Some patrons may not know how to fully use the library's resources. This can be due to individuals' unease in approaching a staff member. Ways in which a library's content is displayed or accessed may have the most impact on use. An antiquated or clumsy search system, or staff unwilling or untrained to engage their patrons, will limit a library's usefulness. In the public libraries of the United States, beginning in the 19th century, these problems drove the emergence of the library instruction movement, which advocated library user education. One of the early leaders was John Cotton Dana. The basic form of library instruction is sometimes known as information literacy.

Libraries should inform their users of what materials are available in their collections and how to access that information. Before the computer age, this was accomplished by the card catalogue—a cabinet (or multiple cabinets) containing many drawers filled with index cards that identified books and other materials. In a large library, the card catalogue often filled a large room.

The emergence of the Internet, however, has led to the adoption of electronic catalogue databases (often referred to as "webcats" or as online public access catalogues, OPACs), which allow users to search the library's holdings from any location with Internet access. This style of catalogue maintenance is compatible with new types of libraries, such as digital libraries and distributed libraries, as well as older libraries that have been retrofitted. Large libraries may be scattered within multiple buildings across a town, each having multiple floors, with multiple rooms housing their resources across a series of shelves called bays. Once a user has located a resource within the catalogue, they must then use navigational guidance to retrieve the resource physically, a process that may be assisted through signage, maps, GPS systems, or RFID tagging.

Finland has the highest number of registered book borrowers per capita in the world. Over half of Finland's population are registered borrowers. In the US, public library users have borrowed on average roughly 15 books per user per year from 1856 to 1978. From 1978 to 2004, book circulation per user declined approximately 50%. The growth of audiovisuals circulation, estimated at 25% of total circulation in 2004, accounts for about half of this decline.

Relationship with the Internet

British Museum Reading Room

A library may make use of the Internet in a number of ways, from creating its own library website to making the contents of its catalogues searchable online. Some specialised search engines such as Google Scholar offer a way to facilitate searching for academic resources such as journal articles and research papers. The Online Computer Library Center allows anyone to search the world's largest repository of library records through its WorldCat online database. Websites such as LibraryThing and Amazon provide abstracts, reviews, and recommendations of books. Libraries provide computers and Internet access to allow people to search for information online. Online information access is particularly attractive to younger library users.

Digitization of books, particularly those that are out-of-print, in projects such as Google Books provides resources for library and other online users. Due to their holdings of valuable material, some libraries are important partners for search engines such as Google in realizing the potential of such projects and have received reciprocal benefits in cases where they have negotiated effectively. As the prominence of and reliance on the Internet has grown, library services have moved the emphasis from mainly providing print resources to providing more computers and more Internet access. Libraries face a number of challenges in adapting to new ways of information seeking that may stress convenience over quality, reducing the priority of information literacy skills. The potential decline in library usage, particularly reference services, puts the necessity for these services in doubt.

Library scholars have acknowledged that libraries need to address the ways that they market their services if they are to compete with the Internet and mitigate the risk of losing users. This includes promoting the information literacy skills training considered vital across the library profession. Many US based research librarians rely on the ACRL Framework for Information Literacy in order to guide students and faculty in research. However, marketing of services has to be adequately supported financially in order to be successful. This can be problematic for library services that are publicly funded and find it difficult to justify diverting tight funds to apparently peripheral areas such as branding and marketing.

The privacy aspect of library usage in the Internet age is a matter of growing concern and advocacy; privacy workshops are run by the Library Freedom Project which teach librarians about digital tools (such as the Tor network) to thwart mass surveillance.

Librarians

See also: Education for librarianship

Libraries are usually staffed by a combination of professionally trained librarians, paraprofessional staff sometimes called library technicians, and support staff. Some topics related to the education of librarians and allied staff include accessibility of the collection, acquisition of materials, arrangement and finding tools, the book trade, the influence of the physical properties of the different writing materials, language distribution, role in education, rates of literacy, budgets, staffing, libraries for specially targeted audiences, architectural merit, patterns of usage, the role of libraries in a nation's cultural heritage, and the role of government, church or private sponsorship. Since the 1960s, issues of computerization and digitization have arisen.

Types

Many institutions make a distinction between a circulating or lending library, where materials are expected and intended to be loaned to patrons, institutions, or other libraries, and a reference library where material is not lent out. Travelling libraries, such as the early horseback libraries of eastern Kentucky and bookmobiles, are generally of the lending type. Modern libraries are often a mixture of both, containing a general collection for circulation, and a reference collection which is restricted to the library premises. Also, increasingly, digital collections enable broader access to material that may not circulate in print, and enables libraries to expand their collections even without building a larger facility. Lamba (2019) reinforced this idea by observing that "today's libraries have become increasingly multi-disciplinary, collaborative and networked" and that applying Web 2.0 tools to libraries would "not only connect the users with their community and enhance communication but will also help the librarians to promote their library's activities, services, and products to target both their actual and potential users".

Academic libraries

Main article: Academic library

 

The University Library at Eötvös Loránd University, Budapest, Hungary

Academic libraries are generally located on college and university campuses and primarily serve the students and faculty of that and other academic institutions. Some academic libraries, especially those at public institutions, are accessible to members of the general public in whole or in part. Library services are sometimes extended to the general public at a fee, some academic libraries create such services in order to enhance literacy levels in their communities.

Academic libraries are libraries that are hosted in post-secondary educational institutions, such as colleges and universities. Their main functions are to provide support in research, consultancy and resource linkage for students and faculty of the educational institution. Academic libraries house current, reliable and relevant information resources spread through all the disciplines which serve to assuage the information requirements of students and faculty. In cases where not all books are housed some libraries have E-resources, where they subscribe for a given institution they are serving, in order to provide backups and additional information that is not practical to have available as hard copies. Furthermore, most libraries collaborate with other libraries in exchange of books.

Specific course-related resources are usually provided by the library, such as copies of textbooks and article readings held on 'reserve' (meaning that they are loaned out only on a short-term basis, usually a matter of hours). Some academic libraries provide resources not usually associated with libraries, such as the ability to check out laptop computers, web cameras, or scientific calculators.

The Robarts Library at the University of Toronto, Canada

Academic libraries offer workshops and courses outside of formal, graded coursework, which are meant to provide students with the tools necessary to succeed in their programs. These workshops may include help with citations, effective search techniques, journal databases, and electronic citation software. These workshops provide students with skills that can help them achieve success in their academic careers (and often, in their future occupations), which they may not learn inside the classroom.

The academic library provides a quiet study space for students on campus; it may also provide group study space, such as meeting rooms. In North America, Europe, and other parts of the world, academic libraries are becoming increasingly digitally oriented. The library provides a "gateway" for students and researchers to access various resources, both print/physical and digital. Academic institutions are subscribing to electronic journals databases, providing research and scholarly writing software, and usually provide computer workstations or computer labs for students to access journals, library search databases and portals, institutional electronic resources, Internet access, and course- or task-related software (i.e. word processing and spreadsheet software). Some academic libraries take on new roles, for instance, acting as an electronic repository for institutional scholarly research and academic knowledge, such as the collection and curation of digital copies of students' theses and dissertations.^[49][50] Moreover, academic libraries are increasingly acting as publishers on their own on a not-for-profit basis, especially in the form of fully Open Access institutional publishers.

Children's libraries

"Children's library" redirects here. For the collection of digitized books, see Internet Archive's Children's Library.

 

A children's library in Montreal, Quebec, Canada in 1943

Children's libraries are special collections of books intended for juvenile readers and usually kept in separate rooms of general public libraries. Some children's libraries have entire floors or wings dedicated to them in bigger libraries while smaller ones may have a separate room or area for children. They are an educational agency seeking to acquaint the young with the world's literature and to cultivate a love for reading. Their work supplements that of the public schools.

Services commonly provided by public libraries may include storytelling sessions for infants, toddlers, preschool children, or after-school programs, all with an intention of developing early literacy skills and a love of books. One of the most popular programs offered in public libraries are summer reading programs for children, families, and adults.

Another popular reading program for children is PAWS TO READ or similar programs where children can read to certified therapy dogs. Since animals are a calming influence and there is no judgment, children learn confidence and a love of reading. Many states have these types of programs: parents need simply ask their librarian to see if it is available at their local library.

National libraries

Main article: National library

 

National Library of Wales, Aberystwyth

A national or state library serves as a national repository of information, and has the right of legal deposit, which is a legal requirement that publishers in the country need to deposit a copy of each publication with the library. Unlike a public library, a national library rarely allows citizens to borrow books. Often, their collections include numerous rare, valuable, or significant works. There are wider definitions of a national library, putting less emphasis on the repository character. The first national libraries had their origins in the royal collections of the sovereign or some other supreme body of the state.

Many national libraries cooperate within the National Libraries Section of the International Federation of Library Associations and Institutions (IFLA) to discuss their common tasks, define and promote common standards, and carry out projects helping them to fulfill their duties. The national libraries of Europe participate in The European Library which is a service of the Conference of European National Librarians (CENL).

Public lending libraries

A community library in Ethiopia

 

Public library in Palma, Balearic Islands

A public library provides services to the general public. If the library is part of a countywide library system, citizens with an active library card from around that county can use the library branches associated with the library system. A library can serve only their city, however, if they are not a member of the county public library system. Much of the materials located within a public library are available for borrowing. The library staff decides upon the number of items patrons are allowed to borrow, as well as the details of borrowing time allotted. Typically, libraries issue library cards to community members wishing to borrow books. Often visitors to a city are able to obtain a public library card.

Many public libraries also serve as community organizations that provide free services and events to the public, such as reading groups and toddler story time. For many communities, the library is a source of connection to a vast world, obtainable knowledge and understanding, and entertainment. According to a study by the Pennsylvania Library Association, public library services play a major role in fighting rising illiteracy rates among youths. Public libraries are protected and funded by the public they serve.

Bates Hall, the main reading room of the Boston Public Library, Boston, Massachusetts, United States

As the number of books in libraries have steadily increased since their inception, the need for compact storage and access with adequate lighting has grown. The stack system involves keeping a library's collection of books in a space separate from the reading room. This arrangement arose in the 19th century. Book stacks quickly evolved into a fairly standard form in which the cast iron and steel frameworks supporting the bookshelves also supported the floors, which often were built of translucent blocks to permit the passage of light (but were not transparent, for reasons of modesty). The introduction of electric lights had a huge impact on lighting in libraries. The use of glass floors was largely discontinued, though floors were still often composed of metal grating to allow air to circulate in multi-story stacks. As more space was needed, a method of moving shelves on tracks (compact shelving) was introduced to cut down on otherwise wasted aisle space.

Library 2.0, a term coined in 2005, is the library's response to the challenge of Google and an attempt to meet the changing needs of users by using Web 2.0 technology. Some of the aspects of Library 2.0 include, commenting, tagging, bookmarking, discussions, use of online social networks by libraries, plug-ins, and widgets. Inspired by Web 2.0, it is an attempt to make the library a more user-driven institution.

Despite the importance ascribed to public libraries, their budgets are often cut by legislatures. In some cases, funding has dwindled so much that libraries have been forced to cut their hours and release employees.

Reference libraries

Main reading room of the New York City Public Library on 5th Avenue c. 1910–1920

A reference library does not lend books and other items; instead, they can only be read at the library itself. Typically, such libraries are used for research purposes, for example at a university. Some items at reference libraries may be historical and even unique. Many lending libraries contain a "reference section", which holds books, such as dictionaries, which are common reference books, and are therefore not lent out. Such reference sections may be referred to as "reading rooms", which may also include newspapers and periodicals. An example of a reading room is the Hazel H. Ransom Reading Room at the Harry Ransom Center of the University of Texas at Austin, which maintains the papers of literary agent Audrey Wood.

Research libraries

Main article: Research library

 

Main reading room of the Rijksmuseum Research Library is the largest public art history research library in the Netherlands. The library is part of the Rijksmuseum in Amsterdam.

 

The Library of Congress is one of the largest research libraries in the world.

A research library is a collection of materials on one or more subjects. A research library supports scholarly or scientific research and will generally include primary as well as secondary sources; it will maintain permanent collections and attempt to provide access to all necessary materials. A research library is most often an academic or national library, but a large special library may have a research library within its special field, and a very few of the largest public libraries also serve as research libraries. A large university library may be considered a research library; and in North America, such libraries may belong to the Association of Research Libraries. In the United Kingdom, they may be members of Research Libraries UK (RLUK). Particularly important collections in England may be designated by Arts Council England.

A research library can be either a reference library, which does not lend its holdings, or a lending library, which does lend all or some of its holdings. Some extremely large or traditional research libraries are entirely reference in this sense, lending none of their materials; most academic research libraries, at least in the US and the UK, now lend books, but not periodicals or other materials. Many research libraries are attached to a parent organization and may serve only members of that organization. Examples of research libraries include the British Library, the Bodleian Library at Oxford University and the New York Public Library Main Branch on 42nd Street in Manhattan, State Public Scientific Technological Library of the Siberian Branch of the Russian Academy of Science.

Digital libraries

Main article: Digital library

Digital libraries are libraries that house digital resources. They are defined as an organization and not a service that provide access to digital works, have a preservation responsibility to provide future access to materials, and provides these items easily and affordably. The definition of a digital library implies that "a digital library uses a variety of software, networking technologies and standards to facilitate access to digital content and data to a designated user community." Access to digital libraries can be influenced by several factors, either individually or together. The most common factors that influence access are: The library's content, the characteristics and information needs of the target users, the library's digital interface, the goals and objectives of the library's organizational structure, and the standards and regulations that govern library use. Access will depend on the users ability to discover and retrieve documents that interest them and that they require, which in turn is a preservation question. Digital objects cannot be preserved passively, they must be curated by digital librarians to ensure the trust and integrity of the digital objects.

One of the biggest considerations for digital librarians is the need to provide long-term access to their resources; to do this, there are two issues requiring watchfulness: Media failure and format obsolescence. With media failure, a particular digital item is unusable because of some sort of error or problem. A scratched CD-ROM, for example, will not display its contents correctly, but another, unscratched disk will not have that problem. Format obsolescence is when a digital format has been superseded by newer technology, and so items in the old format are unreadable and unusable. Dealing with media failure is a reactive process, because something is done only when a problem presents itself. In contrast, format obsolescence is preparatory, because changes are anticipated and solutions are sought before there is a problem.

Future trends in digital preservation include: Transparent enterprise models for digital preservation, launch of self-preserving objects, increased flexibility in digital preservation architectures, clearly defined metrics for comparing preservation tools, and terminology and standards interoperability in real time.

Special libraries

Main article: Special library

 

Bookshelves at the Beinecke Rare Book & Manuscript Library. The top floor contains 180,000 volumes. Since 1977, all new acquisitions are frozen at −33 °F (−36 °C) to prevent the spread of insects and diseases.

Many private businesses and public organizations, including hospitals, churches, museums, research laboratories, law firms, and many government departments and agencies, maintain their own libraries for the use of their employees in doing specialized research related to their work. Depending on the particular institution, special libraries may or may not be accessible to the general public or elements thereof. In more specialized institutions such as law firms and research laboratories, librarians employed in special libraries are commonly specialists in the institution's field rather than generally trained librarians, and often are not required to have advanced degrees in a specifically library-related field due to the specialized content and clientele of the library.

Special libraries can also include women's libraries or LGBTQ libraries, which serve the needs of women and the LGBTQ community. Libraries and the LGBTQ community have an extensive history, and there are currently many libraries, archives, and special collections devoted to preserving and helping the LGBTQ community. Women's libraries, such as the Vancouver Women's Library or the Women's Library @LSE are examples of women's libraries that offer services to women and girls and focus on women's history.

Some special libraries, such as governmental law libraries, hospital libraries, and military base libraries commonly are open to public visitors to the institution in question. Depending on the particular library and the clientele it serves, special libraries may offer services similar to research, reference, public, academic, or children's libraries, often with restrictions such as only lending books to patients at a hospital or restricting the public from parts of a military collection. Given the highly individual nature of special libraries, visitors to a special library are often advised to check what services and restrictions apply at that particular library.

Special libraries are distinguished from special collections, which are branches or parts of a library intended for rare books, manuscripts, and other special materials, though some special libraries have special collections of their own, typically related to the library's specialized subject area.

For more information on specific types of special libraries, see law libraries, medical libraries, music libraries, or transportation libraries.

In the 21st century, there has been increasing use of the Internet to gather and retrieve data. The shift to digital libraries has greatly impacted the way people use physical libraries. Between 2002 and 2004, the average American academic library saw the overall number of transactions decline approximately 2.2%. Libraries are trying to keep up with the digital world and the new generation of students that are used to having information just one click away. For example, the University of California Library System saw a 54% decline in circulation between 1991 and 2001 of 8,377,000 books to 3,832,000.

These facts might be a consequence of the increased availability of e-resources. In 1999–2000, 105 ARL university libraries spent almost $100 million on electronic resources, which is an increase of nearly $23 million from the previous year. A 2003 report by the Open E-book Forum found that close to a million e-books had been sold in 2002, generating nearly $8 million in revenue. Another example of the shift to digital libraries can be seen in Cushing Academy's decision to dispense with its library of printed books—more than 20,000 volumes in all—and switch over entirely to digital media resources.

Stacks of the José Vasconcelos Library in Mexico City, Mexico

A 2001 discussion paper exploring changing use of libraries reported decreased library usage by undergraduate students, who had become more used to retrieving information from the Internet than a traditional library. Finding information by simply searching the Internet is seen as easier and faster than reading an entire book. In a survey conducted by NetLibrary, 93% of undergraduate students said that finding information online made more sense to them than going to the library. Three-quarters said they did not have enough time to go to the library. While the retrieving information from the Internet may be efficient and time-saving than visiting a traditional library, research showed that undergraduates are most likely searching only .03% of the entire web.

In the mid-2000s, Swedish company Distec invented a library book vending machine known as the GoLibrary, that offers library books to people where there is no branch, limited hours, or high traffic locations such as El Cerrito del Norte BART station in California.

Associations

See also: List of library associations

The International Federation of Library Associations and Institutions (IFLA) is the leading international association of library organizations. It is the global voice of the library and information profession, and its annual conference provides a venue for librarians to learn from one another.

Library associations in Asia include the Indian Library Association (ILA), Indian Association of Special Libraries and Information Centers (IASLIC), Bengal Library Association (BLA), Kolkata, Pakistan Library Association, the Pakistan Librarians Welfare Organization, the Bangladesh Association of Librarians, Information Scientists and Documentalists, the Library Association of Bangladesh, and the Sri Lanka Library Association (founded 1960).

National associations of the English-speaking world include the American Library Association, the Australian Library and Information Association, the Canadian Library Association, the Library and Information Association of New Zealand Aotearoa, and the Research Libraries UK (a consortium of 30 university and other research libraries in the United Kingdom). Library bodies such as CILIP (formerly the Library Association, founded 1877) may advocate the role that libraries and librarians can play in a modern Internet environment, and in the teaching of information literacy skills. The Nigerian Library Association is the recognized group for librarians working in Nigeria. It was established in 1962 in Ibadan.

Public library advocacy is support given to a public library for its financial and philosophical goals or needs. Most often this takes the form of monetary or material donations or campaigning to the institutions which oversee the library, sometimes by advocacy groups such as Friends of Libraries and community members. Originally, library advocacy was centered on the library itself, but current trends show libraries positioning themselves to demonstrate they provide "economic value to the community" in means that are not directly related to the checking out of books and other media.

Protection

Libraries are considered part of the cultural heritage and are one of the primary objectives in many state and domestic conflicts and are at risk of destruction and looting. Financing is often carried out by robbing valuable library items. National and international coordination regarding military and civil structures for the protection of libraries is operated by Blue Shield International and UNESCO. From an international perspective, despite the partial dissolution of state structures and very unclear security situations as a result of the wars and unrest, robust undertakings to protect libraries are being carried out. The topic is also the creation of "no-strike lists", in which the coordinates of important cultural monuments such as libraries have been preserved.
