About Us

The mission of the Network of the National Library of Medicine (NNLM) is to advance the progress of medicine and improve public health by providing U.S. health professionals with equal access to biomedical information and improving individuals' access to information to enable them to make informed decisions about their health.

Established in 1965, the NNLM is the field force of the National Libary of Medicine (NLM). We provide health information resources, educational training, and project funding for member organizations. We work with libraries and community-based organizations to support health literacy, advance health equity, improve engagement with research and data, expand professional knowledge, and promote awareness of NLM resources within local communities.

NNLM operations are coordinated through seven Regional Medical Libraries (RMLs) which, in collaboration with funded member organizations, carry out regional and national programs such as training events and outreach activities. Select a U.S. state or territory below to learn more about its NNLM region and RML.

Additionally, there are three National Offices and three National Centers, which serve all seven regions. These are the NNLM Web Services Office (NWSO), the NNLM Training Office (NTO), the NNLM Public Health Coordination Office (NPHCO), the NNLM Evaluation Center (NEC), and the NNLM Center for Data Services (NCDS). 

Regional Medical Libraries, National Offices, and National Centers are collectively known as ROCs.

The overall program is coordinated by the NLM’s User Engagement Program (UEP).
