- Abstract
- This report describes an experiment in subject enhancement conducted at an academic research library. Subjects and contents notes were added to online catalog records for a group of previously uncirculated social science essay collections, and circulation was monitored over one academic year. A control group, plus a third group with added contents notes but no extra subjects, were also monitored. Results showed an improvement in recorded use for the subject-enhanced titles, but not for titles that only had added contents notes. The effects of browsing, keyword searching, and OPAC display are discussed
