This document summarizes a presentation about revising resource sharing policies and opening up library collections for interlibrary loan lending. The presentation discusses the history of interlibrary loan dating back to ancient Alexandria, best practices for efficient lending, strategies for advocating for broader lending policies using data and examples from peer institutions, and considerations for lending different formats like books, microfilm, audiovisual materials, and e-resources both domestically and internationally. The goal is to encourage libraries to change their resource sharing tune and foster a greater sense of community through open collection sharing.
