The revised system specifications described in this document were adopted by the 19 California State University and College (CSUC) libraries for a second test version of the CLSI "Expanded Title Record" public access online catalog at California State University at Chico. Should this pilot demonstration of the data format prove successful, it is expected that implementation of the CLSI public access system at all CSUC campus libraries will follow. The specifications, which assume machine-readable bibliographic input through OCLC archival tapes or LC-MARC compatible formats, are designed to accept and process all OCLC formats and their revisions, including those necessary for compatibility with Anglo American Cataloging Rules, 2nd edition. Included in the document are a list of all variable length data fields, a table in which variable field contents are described, a set of general and specific rules regarding variable field contents, and a description of fixed length field contents. An algorithm for constructing derived author/title keys is described in an appendix. (Author/JL)
