The Association of College and Research Libraries has released the Value of Academic Libraries: A Comprehensive Research Review and Report.
Here's an excerpt from the press release:
Developed for ACRL by Megan Oakleaf of the iSchool at Syracuse University, this valuable resource reviews the quantitative and qualitative literature, methodologies and best practices currently in place for demonstrating the value of academic libraries. The full report, along with supplemental materials, is available online at http://www.acrl.ala.org/value/. . . .
The primary objective of this comprehensive review is to provide academic librarians and institutional leaders with a clearer understanding of what research about the performance of academic libraries already exists and where gaps in this research occur. The report additionally identifies the most promising best practices and measures correlated to performance and represents a starting point to assist college, university and community college librarians in gathering evidence to tell the story of their libraries and promote dialogue on the value of the academic library in higher education. . . .
The full report is now available on the ACRL website, along with a separate executive summary for distribution to campus decision makers, a bibliography of sources consulted in the development of the report, a podcast interview with Hinchliffe and Oakleaf and links to additional resources.
