American Chemical Society

ACS Citation Style is used by journals of the American Chemical Society and by scientific journals in the field of chemistry. For additional citation examples, visit the ACS Style Quick Guide page.

ACS Guidance

Organize your ACS References in one of two distinct ways:

  1. Ordered and numbered in the sequence they are used in the paper. A superscript number (1,2,3) or a number in parentheses (1,2,3) is added in-text wherever the work is referenced.
  2. Ordered alphabetically by the author's last name. In-text citations are added in (Author, Year) format. 

Include up to ten (10) authors in the order they appear - if there are more authors, include "et al." after the tenth author.
