An online survey was sent to academic libraries and consortia with an integrated library system (ILS) migration project, based on review of press releases from major U.S. ILS vendors. This study takes a systematic approach to provide a snapshot of the academic ILS market and key factors affecting the outcome of an ILS migration project. It reveals the challenges and opportunities facing academic libraries and ILS vendors in an environment with rapidly changing technology and increasingly sophisticated academic users.
