The range of roles in healthcare knowledge and library services are many and varied. From 'traditional' librarian roles to those that break new ground, including clinical, embedded and outreach librarians and knowledge management, they are a vital ongoing support for this important sector. This book provides a comprehensive, practitioner focused introduction to all aspects of knowledge and library work in the health sector. Starting with an overview of NHS England and how knowledge and library work sits within it, the book addresses such critical areas as services supporting evidence-based practice, the developing area of health information literacy, collaborative working, demonstrating impact and value and research discovery.
