The ACS style is produced by the American Chemical Society (ACS). ACS offers several ways to make in-text references: with a superscript number, a number in parentheses, or with author name and year of publication in parentheses.
While its emphasis is on chemistry, the ACS style is applicable to science, engineering, and medical disciplines. ACS style uses abbreviated journal names. Names should be abbreviated according to the Chemical Abstracts Service Source Index (CASSI).
