Libraries seek methods of maximizing users' discovery of relevant resources. One of these methods is to enhance bibliographic records with tables of contents. Limited previous research has shown a positive correlation between record enhancement and circulation, but the costs for enhancement can vary widely. The authors present their research in which they examined circulation statistics after retrospectively enhancing records for anthologies of literature with low prior circulation. Results indicate that circulation increased for some subject areas, but not others. The authors conclude that this service is of value to our users, and discuss the issues of costs and selection of items for this kind of project.
