This evaluation of the California Title-Author List (CATALIST), second edition, a union catalog on microfiche published from computer output microform tapes which contains location records for approximately 700,000 titles held in 152 public, academic, and special libraries throughout California, is presented as a means of assessing progress to date and providing information for future planning for three interrelated statewide resource sharing projects involved in the creation and distribution of CATALIST: the California Database-Monographs Project, the Statewide Data Base Program, and the Finding List Project. The evaluation effort includes an analysis of the contents of CATALIST, a general survey of all 251 CATALIST users to obtain usage and effectiveness perceptions, and further collection of data from CATALIST users to ascertain the hit rate of all finding tools used during the interlibrary loan (ILL) search process. In terms of content, CATALIST is determined to be public library oriented. It is further shown that CATALIST receives widespread use in support of interloan services and that it is effective and easy to use. Areas for improvement, notably inclusion of more titles and more evenly distributed geographic coverage, and a variety of factors influencing the future of CATALIST are identified. The report concludes with three appendices: samples of the general survey and data collection forms, and a list of comments received on the impact of CATALIST upon ILL patterns of individual libraries or systems.
