The Elusive User: Changing Use Patterns in Academic Libraries 1995 to 2004 Charles Martell has data that is a bit out of date and not that surprising: cost of journals WAY UP and electronic use UP (exceptions: circulation in Ivy League libraries has gone UP, reference transactions at Columbia UP). There is a great final quote in the conclusion, from another reference, "Among the most critical [frontiers for librarians to explore] are those that facilitate interaction between the virtual user and the library professional." I believe this is a great endorsement for all the Web 2.0, chat, and other related efforts of librarians.
