Karen Bjork, Rebel Cummings-Sauls, and Ryan Otto have published "Opening Up Open Access Institutional Repositories to Demonstrate Value: Two Universities' Pilots on Including Metadata-Only Records" in the Journal of Librarianship and Scholarly Communication.
Here's an excerpt:
INTRODUCTION Institutional repository managers are continuously looking for new ways to demonstrate the value of their repositories. One way to do this is to create a more inclusive repository that provides reliable information about the research output produced by faculty affiliated with the institution. DESCRIPTION OF PROGRAM This article details two pilot projects that evaluated how their repositories could track faculty research output through the inclusion of metadata-only (no full-text) records. The purpose of each pilot project was to determine the feasibility and provide an assessment of the long-term impact on the repository's mission statement, staffing, and collection development policies. NEXT STEPS This article shares the results of the pilot project and explores the impact for faculty and end users as well as the implications for repositories.
