The capacity to understand and communicate health information is a major international health concern. Sponsored by the Health and Biosciences Section of International Federation of Library Associations, this book highlights the contribution that librarians are making to improving health literacy and enabling citizens to be active participants in the management of their own health. Knowledge is power and the World Health Organization recognizes that health literacy, involving effective access to and understanding of health information, is essential to health and well-being in society by empowering and enabling citizens to participate in their own healthcare. The book presents inspiring studies from an international group of authors showing how libraries and librarians are partnering with diverse sectors of society including universities, hospitals, public health clinics, community-based organisations, voluntary bodies and government agencies, to help citizens understand and manage their health. It provides guidance by example to suggest how libraries can help citizens participate in their healthcare and their communities by collaborating with others to increase health literacy in society.
