CD-ROM that substitutes for online databases (ex. Disclosure, Medline), 3. CD-ROM that has some functions such as giving orders for books besides information retrieval (ex. Books in Print Plus), 4. CD-ROM that contains literatures including pictures and figures (ex. ADONIS). The future trends of CD-ROM utilization are also suggested.
