    Abstract
    This short guide describes the process for creating a CD-ROM based üublic access catalog. The authors admit that the material will be outdated by the time of publication, because product specifics change so rapidly. The report is useful, but not completely thorough. Disadvantages to using CD-ROM for public access catalog are listed, but existing methods to overcome these hindrances are not mentioned. The paper also touches on the possibility that CD-ROM-based catalogs may be more than simply an extra service, that they may become full-service catalogs in themselves
