This book examines the changing roles of the librarian and how working within a rich digital environment has impacted on the ability of professionals to develop the appropriate 'know how', skills, knowledge and behaviours required in order to operate effectively. Expert specialists and opinion-makers from around the world discuss the challenges and successes of adapting existing practices, introducing new services and working with new partners in an environment that no longer recognizes traditional boundaries and demarcation of roles. The book is structured thematically, with a focus on three key strands where the impact of digital technologies is significant.
