Standards – Any code of rules or procedures established by national and international library organizations to govern bibliographic control, such as the MARC record format, CIP, and the ISBN/ISSN adopted by the publishing industry. (Reitz, 2004, p. 680)
Standard identifiers – The unique identification number assigned to an edition at the time of first publication, in accordance with an internationally standardized identification system, usually appearing somewhere on the item.

In paperback editions, it appears on the verso of the title page and on the back cover (usually in the lower-right-hand corner). In serials, the International Standard Serial Number (ISSN) appears in the masthead or with the table of contents of each issue or on the copyright page of each volume or part of a series. In printed music, the International Standard Music Number (ISMN) appears on the copyright page.

Statement of International Cataloguing Principles In the interest of efficiency it was determined to hold the regional meetings in five areas of the world that generally would coincide with the IFLA General Meeting held each August. The meetings were held in 2003 in Frankfurt, Germany (European countries and Anglo-American rule makers); 2004 in Buenos Aires, Argentina (Latin American and Caribbean countries); 2005 in Cairo, Egypt (Arabic-speaking Middle Eastern and Northern African countries); 2006 in Seoul, Korea (Asian rule makers and countries); and 2007 in Pretoria, South Africa (Sub-Saharan African countries). This document provides the framework to reach the original goals of IFLA to increase the sharing of bibliographic information across communities, languages, and scripts.

UBC – Universal bibliographic control

UDC – Universal Decimal Classification. The Universal Decimal Classification (UDC) is the world's foremost multilingual classification scheme for all fields of knowledge, a sophisticated indexing and retrieval tool. It was adapted by Paul Otlet and Nobel Prizewinner Henri La Fontaine from the Decimal Classification of Melvil Dewey, and first published (in French) from 1904 to 1907. Since then, it has been extensively revised and developed, and has become a highly flexible and effective system for organizing bibliographic records for all kinds of information in any medium (it is well suited to multi-media information collections). It is structured in such a way that new developments and new fields of knowledge can be readily incorporated. The code itself is independent of any particular language or script (consisting of Arabic numerals and common punctuation marks), and the accompanying class descriptions have appeared in many translated versions. UDC is in worldwide use, and has been published in whole or in part in 23 different languages.
UNESCO – United Nations Educational Scientific and Cultural Organization
UNIMARC – Universal MARC. Standard for the representation and exchange of data in machine-readable form. Maintenance and update of UNIMARC, now a set of four formats – Bibliographic, Authorities, Classification and Holdings – is the responsibility of the Permanent UNIMARC Committee.
Universal bibliographic control and International MARC (UBCIM) – The Universal Bibliographic Control (UBC) programme was set up in 1974 by IFLA to encourage international conformity in the exchange of bibliographic data, following activity from 1969 by cataloguing experts. The international MARC Programme was amalgamated with UBC in 1986 to form UBCIM. Much was achieved, and the programme had become redundant; it was closed in 2003. The UNIMARC format, which had been one of the major projects of UBCIM, is to be continued by the National Library of Portugal.
