AMA Style is the standard for publications of the American Medical Association (AMA), i.e., JAMA and the Archives Journals. It has been widely adopted throughout the medical community. The style modifies but generally follows the guidance of the National Library of Medicine.
The National Library of Medicine (NLM) produces the content for MEDLINE/PubMed, the world's premier medical database. NLM Style provides standards for citing biomedical material and documents the Library's rules for journal citations in MEDLINE/PubMed.
