Written for information professionals and librarians trying to implement and manage Web 2.0 in their physical and online collections, Building Library 3.0 pays careful attention to the implementation of social web applications, mobile computing, and RFID and QR Code technology. The book details both how to make these technologies work for libraries and also explores why libraries must gain ground in the important new territories of Web 2.0. The changing relationships between information seekers, the information being sought, and the professional information gatekeepers is of great importance in this change, and this book explains both the use of the technology to reach information seeking communities, and the profound ways in which such relationships will change the nature of librarianship.
