The majority of NLM's applications are reviewed by the Biomedical Library and Informatics Review Committee (BLIRC) (current members of the BLIRC). Some applications are reviewed by Special Emphasis Panels (SEPs), convened on an ad hoc basis. Reviewers are chosen primarily for their subject domain expertise; most also have considerable experience with the NIH granting process. A second level review is performed by NLM's Board of Regents (current members of the BOR). See Peer Review Roles and Meeting Overview, Peer Review Policies and Practices, and the videos for additional information about the NIH review process.
