NLM Style: Citing Your Sources

A brief guide to the NLM style rules

What is NLM Style?

The National Library of Medicine (NLM) provides assistance to authors in compiling lists of references for their publications, to editors in revising such lists, to publishers in setting reference standards for their authors and editors, and to librarians and others in formatting bibliographic citations in Citing Medicine. Citing Medicine supercedes National Library of Medicine recommended formats for bibliographic citation (1991, 2001).

NLM Style does not include any manuscript styling, including placing citations within text. If you are directed to write a paper using NLM Style, select an in-text system used by a different style and be consistent in your application of this. Use NLM Style to format the list of references at the end of your paper.
