This chapter describes the origins, design and development of the Learning Activity Management System (LAMS) Community. It begins with the history of LAMS as a new kind of e-learning design tool, instantiating in practice many of the principles and possibilities explored in this book. The author – the original developer of LAMS – goes on to discuss new principles for the development of Learning Object Repositories (LORs) as a means of sharing designs and communicating about the practice of design. Again, the LAMS Community is used to explore these principles through a practical and living example. The chapter concludes with some reﬂections on tools and communities for the future.
