Librarians know that interactive technologies are a part of any library's information provision and that many of these technologies may become rapidly outdated and replaced. Patrons only know that they want better and faster access. In this book, the thirteenth in a series from the Library and Information Technology Association, editors Hanson and Cervone address the “hype cycle,” indicating that some of the technologies described in this book may be approaching their apex and that “librarians must learn where the hype stops and reality begins” (page xi), which is a worthy admonition.
