I came across an interesting paper a few days ago. It's a study of digital information seekers, and what makes this paper really interesting is that it was written for academic libraries so they could improve their systems and help users find information better. I found it interesting. From the executive summary:
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 (Screenagers (Rushkoff 1996) and Millennials).
P.S. There is also a 2 page summary which you can find here (PDF).
