Title
Implications of CD-ROMs for reference services in university libraries
Source
Library management. 13(1992) no.3, S.20-28
Year
1992
Abstract
Describes the advantages of CD-ROMs over printed and on-line sources: large storage capacity, relative cheapness and minimum instruction required to undertake searches. Identifies 5 main criteria from the literature which should be considered when introducing this technology into reference libraries. Cost, currency and contents should be considered when comparing their usefulness with other media. At present, CD-ROMs offer the most efficient service when used in conjunction with both printed and on-line media
