A large part of the mission of the National Library of Medicine is to collect, index, and disseminate the world's biomedical literature. Until recently, this related only to serial and monographic material, but as new forms of information appear responsibility for bibliographic control of these also must be assumed by the National Library of Medicine. This paper briefly describes the type of information that will be necessary before descriptive cataloging of computer-based educational materials can be attempted.
