We’re working on yet another shared retention pilot project. You might remember from earlier posts that we entered an agreement with ASERL on its cooperative print journal retention program, now dubbed Scholar’s Trust. While Scholar’s Trust focuses on journal retention, our next project will feature monographs and, initially, will involve the following VIVA libraries: George Mason, Old Dominion, UVA, VCU, JMU, Radford, Germanna Community College, J. Sargeant Reynolds Community College, Mountain Empire Community College, University of Richmond, and Washington & Lee. More institutions may enter the project later on. The group has teamed up with Rick Lugg of Sustainable Collection Services, whose product SCS Greenglass provides users with a web application that allows for more systematic, collaborative, data-driven deselection and print retention practices. Just now in its infancy, the group is calculating the number of circulating monographs per institution. Materials excluded from this project are: government documents, special collections, microfilm, scores, materials from special libraries, and more. The next stage involves pulling together title lists for those records and submitted them to SCS. Greenglass will allow us to compare our titles, in addition to comparing these holdings to Worldcat holdings, HathiTrust holdings, Internet Archive holdings, and titles reviewed in Choice. Ultimately, Greenglass should help us identify scarcely-held titles needing protection and serve as a starting place in strategic, collaborative weeding.
