NLM Style: Official Title "Citing Medicine"

NLM is the official citation style for the Wegman's School of Pharmacy. 

NLM Style - Note about Authors

The Citing Medicine Manual has several comments about how many authors to list in a citation. Officially NLM asks for all authors to be listed, and citations automatically generated from PubMed follow this rule.  However, there are other acceptable options.

Chapter 1 Journals, Box 9 Options for Author Names.  

If space is a consideration, the number of authors may be limited to a specific number, such as the first three authors or first six authors. Follow the last named author by a comma and "et al." or "and others."

Rastan S, Hough T, Kierman A, et al.

Adler DG, Baron TH, Davila RE, Egan J, Hirota WK, Leighton JA, and others.

Chapter 1 Journals. Examples of Citations to Journal Articles.
