Penn State University Libraries loaned out Sony Readers loaded with ebooks to students and faculty. They used virtual machines to simulate 20 separate Sony libraries on 2 computers. Each virtual machine hosted 10 Sony Readers for a total of 100 available. Content was cataloged and the devices circulated for 2 weeks with no renewals or holds allowed. English and first year seminar classes had semester-long loans while others were 2 weeks. Users received instruction and training materials. Surveys and other assessments were used to evaluate the program.
