Abstract
Two earlier studies reported the effect of CD-ROM MEDLINE on online end-user and mediated searching at the Ruth Lilly Medical Library of Indiana University. Since then, RLML has evolved to a CD-ROM MEDLINE network and more recently to a magnetic-tape-based network, and is now experiencing vastly increased numbers of end users as well as a resurgent demand for mediated searches. This article discusses the effect of the network on RLML's searching program and training efforts.
