In spring 2010, authors from the University of Massachusetts Amherst conducted a national survey on digital preservation of Institutional Repository (IR) materials among Association of Research Libraries (ARL) member institutions. Examining the current practices of digital preservation of IR materials, the survey of 72 research libraries reveals the challenges and opportunities of implementing digital preservation for IRs in a complex environment with rapidly evolving technology, practices, and standards. Findings from this survey will inform libraries about the current state of digital preservation for IRs.
