    Abstract
    Reports on a study carried out by the Division of Library Automation, University of California, into the characteristics of use and the success rates of users searching the MELVYL Catalog and Ten-Year databases. Examines a series of user sessions extracted randomly from the MELVYL transaction log and developing a profile of online system use. 1.444 sessions were chosen from 11-17 Apr 92. 3 levels of use were examined: the individual command, the search objective, and the session. Details the findings, and discusses their design implications
