Information systems are central to libraries, and managing information systems is critical to serving library communities. Both a textbook for LIS courses and a handbook for practitioners, this volume thoroughly addresses modern libraries' challenges of integrating information technology. Written by Joseph R. Matthews and Carson Block, both experts on library information systems, this book describes the evolution of library information systems, their enabling technologies, and today's dynamic IT marketplace. It explains specific technologies and related topics, including standards and standards organizations, telecommunications and networks, integrated library systems, electronic resource management systems, repositories, authentication and link verification, electronic resources, and nextgen library systems. Readers will also learn the latest about information systems management, covering technology planning, basic technology axioms, the impact of technology on library services, system selection and implementation, system usability, and general technology management. The final section considers current trends and future developments in LIS, including those related to mobile devices and apps as well as the growth of digital libraries.
