Abstract: Report of a survey 96 (out of 119) US and Canadian member libraries of the Association of Research Libraries (ARL) to determine their use of on-line and CD-ROM data bases, including OPACs. 4 catalogues were identified: on-line mediated searching (97%); CD-ROMs (96%); end-user on-line searching (45%); and locally mounted magnetic tapes (37,5%). The latter option is expected to be the most widely used option in the new future. Although CD-ROM caused some migration from on-line, most migration was from printed sources to CD-ROM. Tables show: on-line hosts most used for intermediary on-line searching; on-line data bases most after searched by intermediaries; end user on-line systems offered by most libraries; the 20 most popular CD-ROM data bases; and the 8 magnetic tape data bases accessible on OPACs
