Transient technology? The future of CD‐ROMs in libraries

In a celebrated article, published in 1990, McSean and Law described CD‐ROM as a ‘transient technology’. This paper provides a starting point for a general discussion on the future role of CD‐ROMs in libraries. An examination of the CD‐ROM market and the range of applications available highlights the popularity of the medium. Technical limitations remain, however, and in some subject areas the lack of currency of the data is a significant drawback. Alternative sources of electronic information, including online, tape leasing, BIDS and storage on hard disc, are explored. Although these alternatives are superior to CD‐ROM in some respects, the latter has a promising future particularly for small full‐text applications, multimedia, and small specialised databases. CD‐ROM should be seen, in general terms, as a replacement for printed material rather than a competitor to other forms of electronic information.
