JISC has released The Digital Information Seeker: Report of the Findings from Selected OCLC, RIN, and JISC User Behaviour Projects.
Here's an excerpt:
There are numerous user studies published in the literature and available on the web. There are studies that specifically address the behaviours of scholars while others identify the behaviours of the general public. Some studies address the information-seeking behaviours of scholars within specific disciplines while others identify the behaviours of scholars of multiple disciplines. There are studies that only address undergraduate, graduate, or post graduate students or compare these individual groups' information seeking behaviours to those of scholars. Still other studies address the behaviors of young adults. . .
In the interest of analyzing and synthesizing several user behaviour studies conducted in the US and the UK twelve studies were identified. These twelve selected studies were commissioned and/or supported by non- profit organizations and government agencies; therefore, they have little dependence upon the outcomes of the studies. The studies were reviewed by two researchers who analyzed the findings, compared their analyses, and identified the overlapping and contradictory findings. This report is not intended to be the definitive work on user behaviour studies, but rather to provide a synthesized document to make it easier for information professionals to better understand the information-seeking behaviours of the libraries' intended users and to review the issues associated with the development of information services and systems that will best meet these users' needs.
