The field of librarianship has a history of involvement in patient education, general literacy and information literacy efforts. This history and prominent placement in communities make libraries and librarians an excellent resource in advancing health literacy practice and research. This chapter provides an overview of health literacy and health information literacy efforts in US libraries over the past two decades. The chapter begins with the description of the role of the US National Library of Medicine in developing resources, programs, and partnerships serving health information needs of the public. It then overviews special training programs for increasing librarians' expertise with health information and health literacy support. The narrative also presents different models of health information outreach programs in diverse communities, focusing on serving special populations that may suffer from health disparities. The second half of the chapter describes libraries' and librarians' health information response to continuously evolving contexts, mediums, and requirements. One subsection describes librarians' outreach effort with cutting-edge technologies, such as virtual worlds and gaming. Another focuses on supporting patients' information needs in clinical settings. Two more describe how libraries meet patrons' health information needs in the context of disaster preparedness and health insurance market place sign-up. While presenting the information, to the extent possible, the chapter draws upon research and evaluation of the effectiveness of different types of programs. It also discusses enablers of successes, limitations of the existing data, and directions for future research.
