The EDUCAUSE Center for Applied Research (ECAR) Study of Undergraduate Students and Information Technology, 2008 is available at http://net.educause.edu/ir/library/pdf/ERS0808/RS/ERS0808w.pdf.
Although this study was done with undergraduate students, it provides useful information relevant to all students in all fields at both the undergraduate and graduate levels. Of particular interest to lawyers and law librarians might be Chapter 4: Ownership of, Use of, and Skill with IT; Chapter 5 IT and the Academic Experience; Chapter 6 Social Networking Sites, and the Bibliography included at the end of the study.
