Abstract

CD-ROM technology has reached the point where just a few discs can equal the holdings of a small print library. Reference works used by librarians in hard copy are available on CD-ROM; encyclopedias, news and periodicals are also in full text on disc. If the appropriate reference is found on disc, searchers need go no further than the CD-ROM being examined. Gives abrief overview of a number of examples of CD-ROMs in each category
