Libraries in the USA and globally are undergoing quiet revolution. Libraries are moving away from a philosophy that is collection-centered to one focused on service. Technology is key to that change. The Patron Driven Library explores the way technology has moved the focus from library collections to services, placing the reader at the center of library activities. The book reveals the way library users are changing, and how social networking, web delivery of information, and the uncertain landscape of e-print has energized librarians to adopt technology to meet a different model of the library while preserving core values. Following an introduction, the first part begins with the historical milieu, and moves on to current challenges for financing and acquiring materials, and an exploration of why the millennial generation is transformational. The second part examines how changes in library practice can create a culture for imagining library services in an age of information overflow. The final chapter asks: Whither the library?
