This document outlines the process of managing a mass collections review at Villanova University, initiated in January 2017 to address the need for more study space and to update outdated resources. The review involved data analysis using OCLC's Greenglass tool, public review opportunities for faculty, and systematic weeding based on specific criteria. Reactions from librarians and faculty varied, with some expressing support for the transparency of the process while others raised concerns about the potential impact of the weeding on available resources.
