Resource Description and Access (RDA) - RDA stands for “Resource Description and Access” and is the title of the standard, that is the successor to AACR2. Anglo-American Cataloguing Rules are considered as the most important advances in English-language codes for descriptive cataloging during the twentieth century. AACR marked a shift from the previous cataloging rules, which were criticized for being too detailed, complex, and mere compilations of rules to handle specific bibliographic cases. ![]() AACR2 standardized cataloging and ensured consistency within the catalog and between the catalogs of libraries using the same code in describing the physical attributes of library materials identically. AACR also provides rules for the formulation of standard forms of names and titles to provide access to and grouping of those descriptions. The rules cover the standard description of areas like, the title, publisher, edition, series, etc., as well as the provision of choice and form of access points (headings) for all materials which a library may hold or to which it may have access, including books, serials, cartographic materials, electronic resources, etc. AACR2 comprise a detailed set of rules and guidelines for producing metadata in a surrogate record to represent a library resource. The second edition of Anglo-American Cataloguing Rules (AACR2) is the most widely used cataloging code, designed for use in the construction of catalogs and other lists in general libraries of all sizes. The revisions and updates of the standard are referred to as AACR2. ![]() It was first developed in 1967 and updated regularly until 2005. Two popular standards for Descriptive Cataloging are Anglo-American Cataloging Rules (AACR) and its successor Resource Description and Access (RDA).Īnglo-American Cataloguing Rules (AACR, AACR2, AACR2R) - Anglo-American Cataloguing Rules (AACR) is the essential international cataloguing code used for descriptive cataloging of various types of information resources by libraries in the United States, Great Britain, Canada, and Australia as well as in many other countries. Descriptive Cataloging enables the user to find and identify a book, by the name of the author, the title, variant titles, etc. In other words, it is the process of creating metadata about library resources, which is included in theĪ catalog is an organized compilation of bibliographic metadata that represents the holdings of a particular institution or a library network and/or resources accessible in a particular location.Ĭataloging, traditionally, has been seen as comprising two specific activities: Descriptive Cataloging and Subject Cataloging.ĭescriptive Cataloging or Descriptive Cataloguing includes recording the attributes of a library item, such as the name of author(s), contributor(s), title, edition, publisher, distributor, date, the number of pages, its size, name of series, etc. Introduction to Cataloging and Classification, 11th ed., Santa Barbara, CA: Libraries Unlimited. It can be defined as, “The process of creating metadata for resources by describing a resource, choosing name and title access points, conducting subject analysis, assigning subject headings and classification numbers, and maintaining the system through which the cataloging data is made available.”-Joudrey, Taylor, and Miller (2015). In libraries, metadata creation is often called cataloging¹.Ĭataloging is a subset of the larger field called information organization. The process of cataloging involves three major activities, namely, Descriptive Cataloging, Subject Cataloging, and Authority Control. Relative to the movement of materials within technical services, cataloging usually follows the receipt of ordered books in acquisitions. The catalog may be in tangible form, such as a card catalog or in electronic form, such as online public access catalog (OPAC). Cataloging or Cataloguing or Library Cataloging is the process of creating and maintaining bibliographic and authority records in the library catalog, the database of books, serials, sound recordings, moving images, cartographic materials, computer files, e-resources etc.
