As digital libraries expand in their proliferation, and as researchers, students, and consumers increasingly depend on them for their information needs, developers are keen to learn more about the design, use, and usability of these systems. The Handbook of Research on Digital Libraries: Design, Development, and Impact is the single academic reference work to provide comprehensive coverage of digital libraries. Through predictions of future trends, examinations of techniques and technologies, and focuses on users, interactions, and experiences, this in-depth collection provides developers and scholars with an extensive collection of research articles from the expanding field of digital libraries.
