CD‐ROM Public Access Catalogs: Database Creation and Maintenance

Abstract

Preparation of bibliographic data for the production of CD‐ROM public access catalogs (PACs) requires several services: merging records from various vendors or libraries, the elimination of duplicate records, the identification and decoding of holdings information, updating the database (often in an offline mode), and authority control. The nature of specific CD‐ROM catalogs affects the priorities for processing the database. For example, some systems exploit controlled vocabulary and cross references, making subject authority critical. Others provide powerful Boolean searching on key words derived from all parts of the bibliographic record; as a result, the need for quality control checks beyond those typically provided by library vendors is increased. This article identifies the services and processes offered by seven vendors that provide CD‐PACs and one vendor that processes MARC bibliographic databases.
