I like the idea of a Stack View program for virtual browsing and the circulation heat map of the other books on the virtual shelf.
For the Palfrey presentation and the Ithaka webinar, you can see some screenshots I grabbed from the sessions. (The images are copyright of the ACRL, John Palfrey and Ithaka.) If you would like to see the whole presentation and all of the data, then you should watch the recorded webinars.
One hour later, I attended the Ithaka discussion concerning Chapter 3 of their report, Faculty Survey 2009. They did a good job of delving into scholarly communication issues and how faculty think and feel about those issues. It was interesting to see how faculty in different disciplines viewed tenure and promotion practices.
It was also interesting to see how people in different disciplines deposit to and use institutional repositories.
They also looked at how faculty view the importance of scholarly societies. At the very end of the webinar, they mentioned the report that Dr. Diane Harley co-wrote, "Assessing the Future Landscape of Scholarly Communication: An Exploration of Faculty Values and Needs in Seven Disciplines".
