Serials information on CD‐ROM: A reference perspective Available to Purchase

Since its introduction as a library resource in 1984, the use of CD‐ROM technology has proliferated. With ongoing enhancements and a multitude of vendors offering their products on CD‐ROM, this technology is making an impact on the provision of many types of library services. Two major suppliers of serials information have now jumped on the CD‐ROM bandwagon. Beginning in 1987, the entire databases of Ulrich's International Periodicals Directory and Ulrich's Irregular Serials and Annuals have been available on CD‐ROM as Ulrich's PLUS. In 1988, EBSCO introduced the CD‐ROM version of its printed source of serials information, The Serials Directory. This study examines implications for the use of these periodical directories as reference tools and presents a comparison of the two systems.
