Specialized Information Services

National Library of Medicine
As the National Library of Medicine (NLM) implements its Strategic Plan, 2017-2027, it is making organizational changes that include the closure of the Specialized Information Services (SIS) division, effective June 30, 2019, and the transition of many SIS programs into other parts of NLM. This integration serves to not only improve discoverability of and access to SIS resources by NLM's broad set of users, but also enables NLM to leverage its talents and resources to improve overall efficiency and effectiveness.

Over the next few months, some SIS resources and programs will transition to other parts of NLM, be integrated into other NLM resources, made accessible on partner sites, or discontinued. We will provide notice of these changes as they are made. Links to SIS resources and programs in their new locations will be shared here on the SIS homepage.

Questions about this transition and individual resources may be directed to or 1-888-346-3656.
