This book links knowledge management literature and information systems research to explore the process of knowledge preservation within a community of practice. It contributes to existing literature in different ways. First, it provides a conceptualization of the "community knowledge preservation" process. In contrast to previous knowledge management research, knowledge preservation is thus viewed as a process in its own right rather than an integral part of knowledge creation and sharing. Furthermore, the book also investigates how communities of practice preserve knowledge, by identifying the main mechanisms and tools enabling members to select, store and actualize the explicit and tacit forms of collective knowledge. More in general, the book presents guidance on how to use communities of practice to ensure the preservation of knowledge in development processes, for individuals and organizations alike.
