Throughout its history, the National Library of Medicine traditionally focused its programs and services on health care professionals. In the 1990s, the Library recognized that the general public was becoming an important user group, due to the increasing availability of Internet access.[3] This new user group needed access to reliable health information in a consumer-friendly, Web-based format.[4] The National Library of Medicine sought to meet this need with the introduction of MedlinePlus in October 1998.

MedlinePlus debuted with 22 English-language health topics. Today, it has over 800 health topics in English and Spanish and also includes links to health information in over 40 languages.

The site has received numerous awards and media recognition for its quality and usefulness.[5] The site consistently scores highly in the American Customer Satisfaction Index.[6]
