Three years ago, when K-12 schools started thinking seriously about creating digital libraries, the Mesquite Independent School District (TX) bought several Sony eReaders, loaded them with books, and circulated them to students. This initial attempt was not a rousing success. After the Mesquite ISD pulled the plug on its disastrous e-reader lending program, the district, still intent on building a library of digital content, decided to focus its approach only on loading popular materials onto student-owned devices. When a librarian at a neighboring district introduced them to OverDrive's e-book offerings, which operate more like a traditional lending library, Mesquite looked into it and decided to give it a try. School librarians nationwide are asking themselves questions as they move into an era in which students more or less "expect" their favorite books to be available in a digital format. And while print books continue to be the mainstay in most K-12 libraries, districts like Mesquite ISD are serving up some more flexible options. (Contains 8 online resources.)
