OCLC, a company that has provided cataloging and computer-based services to libraries for years, has also published a number of important reports having to do with the "place" of libraries in the information age.
OCLC's 2005 report, Perceptions of Libraries and Information Resources, made headlines with its finding that "books are the library brand." This report has been updated for 2010. The full report is too big (29.3 mb) for this site, but if you're interested you can download it here. Attached are two sections that seemed most relevant to what we're doing, one about books/reading (once again, the library brand!), the other about the library as a community resource.
