National Network of Libraries of Medicine Fact Sheet

The National Network of Libraries of Medicine (NN/LM) is a nationwide program coordinated by the National Library of Medicine (NLM). The mission of the NN/LM is to advance the progress of medicine and improve the public health by: 1) providing all U.S. health professionals equal access to biomedical information and, 2) improving the public's access to information, enabling them to make informed decisions about their health and healthcare. 

The Network consists of over 6,000 member organizations.  These include academic medical libraries, hospital, pharmaceutical and other special health sciences libraries, information centers, public libraries and community-based organizations with an interest in promoting access to health information.  Eight Regional Medical Libraries (RMLs), major institutions under contract with the National Library of Medicine, assist NLM with providing timely access to quality biomedical and health information. In addition to the RML contracts, NLM funds contracts for three national centers, the National Library of Medicine Training Center (NTC), the Outreach Evaluation Resource Center (OERC) and the Web Services Technology Operations Center. 

In support of the Network, the RMLs plan, promote and implement programs, services and outreach within their geographic regions as well as cross-regional collaborative activities. 

Network Membership:

There are two categories of membership within the NN/LM: Full Member and Affiliate Member. A Full Member can be any health sciences library or health-related information center, institution, or organization that: (1) is regularly staffed; (2) has an Internet connection; (3) has its own collection of health sciences materials (books, journals, audiovisuals, electronic databases); (4) provides information services to health professionals and/or the general public; (5) participates in borrowing and lending in DOCLINE. Members are encouraged to provide document delivery service to their own users and/or to unaffiliated users.
An Affiliate Member is a library, information/resource center or organization that promotes health information, education, and/or access, but does not meet all of the criteria for Full Member participation.

Conditions of Network Membership Participation:

Each Full Member and Affiliate Member institution must agree to make the following contributions:

  • Designate an individual as the local contact person for network information/communications.
  • Be listed in the national directory of network members. National directory information is available online through the membership file NN/LM Members Directory.
  • Provide up-to-date information about services and/or collections (where applicable) to NLM and to their Regional Medical Library (RML).

Benefits of Membership:

  • A certificate recognizing NN/LM membership
  • Access to a variety of training opportunities
  • The opportunity to network with other NN/LM members
  • Access to the latest health related news and information
  • Access to the interlibrary loan systems used by health sciences librarians and NLM
  • Posters, brochures, bookmarks, and other promotional materials
  • Eligibility for funding for health information access and other projects
  • The opportunity to provide input on regional NN/LM programs and services

Additional Information about the National Network of Libraries of Medicine can be obtained at, or by contacting your Regional Medical Library (1-800-338-7657).

Document Delivery:

The DOCLINE and Loansome Doc system link Network libraries together to provide biomedical information to members, health professionals, especially underserved health professionals and consumers.  DOCLINE, the National Library of Medicine's free automated interlibrary loan request routing and referral system, provides efficient document delivery service among libraries in the NN/LM. Loansome Doc is a document delivery service offered to health professionals by participating DOCLINE libraries. The RMLs coordinate DOCLINE membership, services and training for their respective regions. 

Emergency Preparedness:

The NN/LM and NLM work together to ensure continuous access to health information and effective use of libraries during large-scale threats, both acts of nature and humans.  The NN/LM provides assistance to its members in preparing for and responding to disasters or localized emergencies.  The NN/LM staff helps with all emergency preparedness and response activities, from risk assessment, to training to developing a disaster plan.


Funding awarded to the NN/LM members through the RMLs supports a wide variety of outreach projects.  The projects are directed at providing training, presentations, demonstrations, technology improvement and exhibits to targeted populations including health professionals, the public health workforce and special populations such as minorities, inner city and rural consumers, K-12 students, seniors, veterans, caregivers and others.  Most of the projects involve partnerships between health sciences libraries and other organizations, including public libraries, public health departments, professional associations, schools, churches, and other community-based organizations.  Representative projects are listed here:  


The Network is the core component of NLM's outreach program and its efforts to reduce health disparities and improve health information literacy.  The outreach program helps to assure that researchers, health professionals and the public are aware of and make effective use of health information available from NLM and the NN/LM.  Through, training, demonstrations, exhibits and other types of public programs, the NN/LM reaches out to health care professionals and consumers to promote the biomedical resources of NLM. Network members collaborate with other libraries including public libraries, local communities and community-based organizations.   NN/LM outreach efforts focus on meeting the needs of minority and underserved populations and the health professionals who serve them including multi-lingual, multicultural information resources.


The NN/LM offers classes, resources, tools, services and support in technologies such as online classes, videoconferencing, social networking and Web-based information and updates.


The RMLs, NTC and OERC offer e-learning and in-person classes to support the effective use of NLM information products and services by health sciences librarians, public librarians, health professionals and the public health workforce.  They provide leadership to the Network related to e-learning delivery methods, instructional best practices for adult learners and support of programs that prepare librarians to meet the needs and challenges of filing new roles.
