This article on cataloging discusses the current and projected future status of the MARC record, with reference to standards, current developments in record formats, and the impact of FRBR on the bibliographic community. A Catalogue is a list of documents, arranged according to some definite plan, which records and describes the resources of a collection. A Union catalogue is a catalogue of the holdings, partial or complete, in a number of document collections, which provides the location of the items held.
