Tablet computer ownership on university campuses has tripled in the past year, according to a Pearson Foundation survey in March 2012. At the threshold of the Post-PC era, as students expectations change, reference and instruction librarians are responding with new services. In this issue of Library Technology Reports Virginia Tech librarians Miller, Meir, and Moorfield-Lang offer a collection of first-hand accounts of academic library projects using tablets.

Library Technology Reports, volume 51, no.7, "Mobile Devices: Service with Intention," edited by Rebecca K. Miller, Heather Moorefield-Lang, and Carolyn Meier, gathers five case studies that discuss the potential of tablets, smartphones, and other mobile devices alongside real-world constraints. From a range of institutional settings, the case studies address three general areas of library work: (1) circulation and lending; (2) teaching and learning; (3) access and design. Assessment is a common theme in the case studies.
