    Abstract
    Index Medicus, the abstract periodical published by the National Library of Medicine, could until recently only be consulted either in its printed version or on-line (Medline). Several versions of Medline on CD-ROM are now available, and the Biomedical Working Group of VOGIN (the Dutch Association of Users of Online Information Systems) has prepared this detailed comparison. Although CD-ROM is becoming more popular, many people are still unfamiliar with the new medium, and a number of authors have discussed the advantages and disadvantages of CD-ROM when compared with its on-line and printed equivalents.
