From November 1981 to April 1983, OCLC's Office of Research has been conducting research into online public access catalogs (OPACs). This project has been funded in part by the Council on Library Resources, Inc. as an attempt to provide new insight into the use of online catalogs by obtaining information which may serve as input for better system design of(More)
