As simple to use as a card catalogue: can you put your library catalogue on CD‐ROM?

Scope This article surveys the systems currently available here and in the US for using CD‐ROM technology to produce working library catalogues; it investigates whether it is worthwhile for individual libraries to consider CD‐ROM as a medium for the production of their own catalogues. We have included systems where an individual library's catalogue is searchable as though it were separate even though it is in fact embedded in a union catalogue of some kind.
