This document discusses the history, purpose, and types of library catalogs. It defines a library catalog as a list of documents in a library collection. Catalogs serve the purposes of retrieval and inventory. There are two main types of catalogs: by creation of entries (alphabetical, classified, alphabetical-classed) and by filling of entries (cards, books, microforms, online). Physical forms include conventional (registers, books, cards) and non-conventional (microforms, online catalogs). Factors like users, collection size, access policies, and resources determine the best catalog type for a library.
