The University of Massachusetts Amherst Libraries established their institutional repository (IR), ScholarWorks@UMass Amherst, in 2006, and we began by systematically populating it with electronic theses and dissertations (ETDs). We currently have a little over 4,500 dissertations and theses in our IR, and they are some of the\ most highly used content in our repository. Through a partnership with the Graduate School, we collect and disseminate all of our current master’s theses and doctoral dissertations through ScholarWorks. We recently launched an ambitious project to scan all 24,000 of our print dissertations and theses and upload them to our IR. In this chapter we will outline the details of our retrospective digitization project as well as our policies and procedures for collecting current ETD submissions. We will also discuss our recent decision to stop requiring our graduate students to submit their dissertations to ProQuest and the reasons we decided to make this change.
