title: On-line literature searching: comparison of PaperChase and National Library of Medicine data bases.
abstract: Two computerized retrieval systems--the National Library of Medicine (NLM) data bases (MEDLINE, TOXLINE, and their respective backfiles) and PaperChase (PC), a subset of the NLM data base, were compared. Comparative parameters of retrieval and costs for literature searching performed on each system were evaluated. Objective measures were used in the evaluation, as well as a subjective assessment of user satisfaction with each system. Data indicate that NLM is a faster and more direct search procedure for a trained individual, making it a more favorable choice in a drug information center. PC is a valuable tool for sites requiring or offering on-line access to many different people searching infrequently. Because P & T Committees must have access to comprehensive and timely literature, knowledge of various retrieval systems is beneficial.
