The goal of the 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 individual's access to information to enable them to make informed decisions about their health.
Eight Health Sciences Libraries function as the Regional Medical Library (RML) for their respective region. The RMLs coordinate the operation of a Network of Libraries and other organizations to carry out regional and national programs. The RMLs ensure a continuity of quality service for core programs of the NNLM, and cooperatively design, implement and evaluate innovative approaches to serve the health information needs of health professionals and a diverse public. Additionally, there are five NNLM National Offices, which serve all members in all eight regions. These offices are the NNLM DOCLINE Coordination Office (NDCO), the NNLM Web Services Office (NWSO), the NNLM Training Office (NTO), the NNLM Evaluation Office (NEO), and the NNLM Public Health Coordination Office (NPHCO).
The overall program is coordinated by the NLM’s National Network Coordinating Office (NNCO). Further the National Network Steering Committee (NNSC), composed of NNCO staff and representatives from each RML, the NNLM National Offices, and NLM staff implements common operational and evaluation processes for the RMLs and NNLM National Office programs they coordinate.
