Abstract

Since its introduction as a library resource in 1984, the use of CD-ROM technology has proliferated among a multitude of vendors. In 1987, Ulrich's, a major supplier of serials information, jumped on the bandwagon when the entire data bases of Ulrich's International Periodicals Directory and Ulrich's Irregular Serials and Annuals become available on CD-ROM as Ulrich's Plus. The next year, Ebsco introduced The Serials Directory in CD-ROM version. Examines and compares these data base systems as reference tools.
