In order for catalogues to function in the most efficient and effective way, it is important that entries are constructed in a consistent way. Over the years, a number of sets of cataloguing rules have been devised to ensure that catalogue records are created in a consistent manner.
Anglo-American Cataloguing Rules (AACR)
Functional requirements for Bibliographic records (FRBR)
International Standard Bibliographic Description (ISBD)
Regeln fur die alphabetische Katalogisierung (RAK)
Cataloguing Cultural Objects (CCO)
