“The National Library of Medicine (NLM), on the campus of the National Institutes of Health in Bethesda, Maryland, has been a center of information innovation since its founding in 1836. The world’s largest biomedical library, NLM maintains and makes available a vast print collection and produces electronic information resources on a wide range of topics that are searched billions of times each year by millions of people around the globe. It also supports and conducts research, development, and training in biomedical informatics and health information technology. In addition, the Library coordinates a 6,000-member National Network of Libraries of Medicine that promotes and provides access to health information in communities across the United States.”

The Mission Statement for the Library:

“The National Library of Medicine (NLM), in Bethesda, Maryland, is a part of the National Institutes of Health, US Department of Health and Human Services (HHS). Since its founding in 1836, NLM has played a pivotal role in information innovation, and in translating biomedical research into practice to improve the public health.

NLM is the world’s largest biomedical library and the developer of electronic information services that deliver trillions of bytes of data to millions of scientists, health professionals and members of the public around the globe, every day. Anyone can search or download free information directly from the NLM website, find it via a search engine, or use an “app” that provides value-added access. External computer systems use NLM applications programming interfaces to obtain NLM data for commercial products and in research. NLM is one of the Federal government’s largest providers of digital content, dispatching an average of more than 6,500 million bits of data per second.

The Library is open to all and has many services and resources. Its digital and physical collections include books, journals, manuscripts, images, and multimedia; genomic, chemical, toxicological, and environmental data; drug information; clinical trials data; health data standards; software; and consumer health information.

In today’s increasingly digital world, NLM carries out its mission of enabling biomedical research, supporting health care and public health, and promoting healthy behavior by:

  • Acquiring, organizing, and preserving the world’s scholarly biomedical literature;
  • Providing access to biomedical and health information across the country in partnership with the 6,400-member National Network of Libraries of Medicine (NN/LM®);
  • Serving as a leading global resource for building, curating and providing sophisticated access to molecular biology and genomic information, including those from the Human Genome Project and NIH Common Fund;
  • Creating high quality information services relevant to toxicology and environmental health, health services research, and public health;
  • Conducting research and development on biomedical communications systems, methods, technologies, and networks and information dissemination and utilization among health professionals, patients, and the general public;
  • Applying Big Data and technology to improve health, analyzing the immense quantities of scientific data available from NLM and other sources, including multiple sources of de-identified prescription and patient outcome data, and applying deep knowledge of clinical terminology and natural language processing, as well as the Library’s rich terminology resources and tools;
  • Funding advanced research in biomedical informatics and data science; and
  • Supporting training and career development, including pre- and post-doctoral research training in biomedical informatics and data science, and specialized training for librarians”

National Network of Libraries of Medicine:

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 the 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 (link is external) (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. Information Technology and Health Data Standards at NLM
