An evaluation of four end-user systems for searching MEDLINE.

This study compared features and determined which of four end-user systems (PaperChase, GRATEFUL MED, Med-Base, or Compact Cambridge: MEDLINE) would best serve the Medical Sciences and Optometry Libraries of Indiana University in providing biomedical information to faculty and graduate students through MEDLINE. Cost, ease of use, retrieval, training needs, equipment requirements, and adequacy of documentation were examined. The study consisted of a comparison of the features of each system based on available documentation; a controlled search performed by the investigators on each system and on regular NLM MEDLINE; and a user study based on observations, questionnaires, and interviews with eleven library patrons who performed the same search of their choice on each of the four systems.
