Abstract

W.S. Cooper's utility theory was used to evaluate end user and mediated searching of online and CD-ROM databases. The searches were conducted by 510 end users, using MEDLINE. The relevance of the references and the usefulness of the documents retrieved were examnied. The study also assessed the perceived value to end users of the information retrieved. Mediated online searching cost 3 times as much as end user CD-ROM searching, but was only about twice as effective in terms of user satisfaction; user convenience should be a high priority for the information provider and mediated CD-ROM searching may be the best compromise currently available as regards cost effectiveness and successful information retrieval for end users
