A library catalog (or library catalogue) is a register of all bibliographic items found in a library or group

of libraries, such as a network of libraries at several locations. A 

bibliographic item can be any information entity (e.g., books, computer files, graphics, realia, cartographic materials, etc.) that is considered library material (e.g., a single novel in an anthology), or a group of library materials (e.g., a

trilogy), or linked from the catalog (e.g., a webpage) as far as it
is relevant to the catalog and to the users (patrons) of the library.

The card catalog was a familiar sight to library users for generations, but it has been effectively replaced by the [[online public

access catalog]] (OPAC). Some still refer to the online catalog as a 

"card catalog". Some libraries with OPAC access still have card catalogs on site, but these are now strictly a secondary resource and are seldom updated. Many of the libraries that have retained their physical card catalog post a sign advising the last year that the card catalog was updated. Some libraries have eliminated their card catalog in favour of the OPAC for the purpose of saving space for other use, such as additional shelving.

Goal

Charles Ammi Cutter made the first explicit statement regarding the objectives of a bibliographic system in his [http://books.google.com/books?id=rj-f4-Ps-AkC&printsec=frontcover Rules for a Printed Dictionary Catalog] in 1876. According to Cutter, those objectives were

1. to enable a person to find a book of which either (Identifying objective)

• the author
• the title
• the subject
• the category

is known.

2. to show what the library has (Collocating objective)

• by a given author
• on a given subject
• in a given kind of literature

3. to assist in the choice of a book (Evaluating objective)

• as to its edition (bibliographically)
• as to its character (literary or topical)

These objectives can still be recognized in more modern definitions formulated throughout the 20th century. 1960/61 Cutter's objectives were

revised by Lubetzky and the Conference on Cataloging Principles (CCP) 

in Paris. The latest attempt to describe a library catalog's goals and functions was made in 1998 with [[Functional Requirements for Bibliographic Records]] (FRBR) which defines four user tasks: find, identify, select, and obtain.

History

A card catalog in the [[University Library of Graz]]

Library catalogs originated as manuscript lists, arranged by format (folio, quarto, etc.) or in a rough alphabetical arrangement by author. Printed catalogs, sometimes called dictionary catalogs, began to be published in the early modern period and enabled

scholars outside a library to gain an idea of its 

contents. Copies of these in the library itself would sometimes be interleaved with blank leaves on which additions could be recorded, or bound as guardbooks in which slips of paper were bound in for new entries. Slips could also be kept loose in cardboard or tin boxes, stored on shelves. The first [[index card|card catalogs]] appeared in the late 19th century after the standardization of the 5 in. x 3 in. card for personal filing systems, enabling much more flexibility, and towards the end of the 20th century the Online public access catalog was developed (see below). These gradually became more common as some libraries progressively abandoned such other catalog formats as paper slips (either loose or in sheaf catalog form), and guardbooks. The beginning of the Library of Congress's catalog card service in 1911 led to the use of these cards in

the majority of American libraries. An equivalent scheme in the United 

Kingdom was operated by the British National Bibliography from 1956 and

was subscribed to by many public and other libraries.

• c. 245 BC: Callimachus is considered the first bibliographer and

is the one that organized the library by authors and subjects. The Pinakes (Ancient Greek: Πίνακες "tables") was the first ever library catalogue. Variations on this system were used in libraries until the late 1800s when Melvil Dewey developed the Dewey Decimal Classification in 1876, which is still in use today.

• c. 800: Library catalogues are introduced in the House of Wisdom

and other medieval Islamic libraries where books are organized into specific genres and categories.

• 1595: Nomenclator of Leiden University Library appears, the

first printed catalog of an institutional library.

• 1674: Thomas Hyde's catalog for the Bodleian Library.
• 1791:

Sorting

In a title catalog, one can distinguish two sort orders:

• In the grammatical sort order (used mainly in older catalogs), the

most important word of the title is the first sort term. The importance
of a word is measured by grammatical rules; for example, the first noun
may be defined to be the most important word.

• In the mechanical sort order, the first word of the title is the

first sort term. Most new catalogs use this scheme, but still include a trace of the grammatical sort order: they neglect an article (The, A, etc.) at the beginning of the title. The grammatical sort order has the advantage that often, the most important word of the title is also a good keyword (question 3), and it is the word most users remember first when their memory is incomplete. However, it has the disadvantage that many elaborate grammatical rules are needed, so that only expert users may be able to search the catalog without help from a librarian.

In some catalogs, person's names are standardized, i. e., the name of the person is always (cataloged and) sorted in a standard form, even if it appears differently in the library material. This standardization is achieved by a process called authority control. An advantage of the

authority control is that it is easier to answer question 2 (which 

works of some author does the library have?). On the other hand, it may be more difficult to answer question 1 (does the library have some specific material?) if the material spells the author in a peculiar variant. For the cataloguer, it may incur (too) much work to check whether Smith, J. is Smith, John or Smith, Jack.
For some works, even the title can be standardized. The technical term for this is uniform title. For example, translations and re-editions are sometimes sorted under their original title. In many catalogs, parts of the Bible are sorted under the standard name of the book(s) they contain. The plays of William Shakespeare are another frequently cited example of the role played by a uniform title in the library catalog.

Many complications about alphabetic sorting of entries arise. Some examples:

• Some languages know sorting conventions that differ from the language

of the catalog. For example, some Dutch catalogs sort

IJ as Y. Should an English catalog follow this suit? And should
a Dutch catalog sort non-Dutch words the same way?

• Some titles contain numbers, for example [[2001: A Space Odyssey

(novel)|2001: A Space Odyssey]]. Should they be sorted as numbers, or spelled out as Two thousand and one?

• de Balzac, Honoré or Balzac, Honoré de?

Ortega y Gasset, José or Gasset, José Ortega y? For a fuller discussion, see collation.

In a subject catalog, one has to decide on which [[library classification|classification]] system to use. The cataloguer will select appropriate subject headings for the bibliographic item and a unique classification number (sometimes known as a "call number") which is used not only for identification but also for the purposes of shelving, placing items with similar subjects near one another, which aids in browsing by library users, who are thus often able to take advantage of serendipity in their search process.

Online catalogs

Dynix]], an early but popular and long-lasting online catalog.

[[File:Card Division of the Library of Congress 3c18631u original.jpg|thumb|right|People working in Card Division, [[Library of Congress]], Washington, D.C., 1910s or 1920s]] Online cataloging, such as Dynix, has greatly enhanced the usability of catalogs, thanks to the rise of MAchine Readable Cataloging = MARC standards in the 1960s. Rules governing the creation of catalog MARC records include not only formal cataloging rules like AACR2 but also special rules specific to MARC, available from the Library of Congress and also OCLC. MARC was originally

used to automate the creation of physical catalog cards; Now the MARC 

computer files are accessed directly in the search process. OPACs have enhanced usability over traditional card formats because:

1. The online catalog does not need to be sorted statically; the user can

choose author, title, keyword, or systematic order dynamically.

1. Most online catalogs offer a search facility for any word of the

title; the goal of the grammatic word order (provide an entry on the word that most users would look for) is reached even better.

1. Many online catalogs allow links between several variants of an author

name. So, authors can be found both under the original and the 

standardised name (if entered properly by the cataloguer).

1. The elimination of paper cards has made the information more

accessible to many people with disabilities, such as the [[visually impaired]], wheelchair users, and those who suffer from [[Mold health issues|mold]] allergies.
