Two surveys worth looking at. One by Ithaka S+R and one by BL/JISC.
The Ithaka S+R report:
Faculty Survey 2009: Key Strategic Insights for Libraries, Publishers, and Societies (April 7, 2010) at
The BL/JISC report:
Researchers of Tomorrow:A three year (BL/JISC) study tracking the research behaviour of 'Generation Y' doctoral students. Annual Report 2009-2010 (June 2010) at
Each is excellent and worth reading, but my first impression is that nothing here is surprising. Digital technologies are transforming scholarship and communication and the relation of libraries (and archives and musuems) to scholars (faculty and graduate students) is changing. The need for libraries as direct intermediaries between scholars and local collections is lessening. Digital technologies present new opportunities for scholarship and communication, but institutions--publishers, societies, libraries, universities--have been slow to capitalize on them in any coordinated way. Researcher behaviors have adapted to the new technologies and have as yet held on to traditional attitudes, values and skills per evaluation and use of sources.
