Michael, You may already be aware of this, but Clifford Lynch did some research last year on this topic (or close enough as to be potentially very useful). Not sure if CNI could provide the data behind the report.

Your responses will help us determine how best to focus efforts in an ongoing project. Though we're mainly concerned with institutions in the United States, all responses are welcome. This short survey has just 5 questions and should take only a moment of your time. We'd really appreciate your participation. https://docs.google.com/a/umn.edu/forms/d/e/1FAIpQLSedNoNWPq1EcLk6ZB1yfJiCAY9tbkCqSfDJLjOAHm4BKOD1Mg/viewform Thank you, -- ++++++++++++++++++++ Michael Berkowski University of Minnesota Libraries 612.626.6137 PGP Public Key: http://z.umn.edu/mjbpubkey ++++++++++++++++++++
