American Chemical Society style book

ACS Style Guide

Developed by the American Chemical Society, this style may be used for research papers in the field of chemistry.

This guide provides examples of the most commonly cited types of sources used by Williams College students. For additional examples and explanations, see The ACS Style Guide or the print manual at Schow Reference QD8.5 .A25 2006.

Each citation consists of two parts: the in-text citation, which provides brief identifying information within the text, and the reference list, a list of sources that provides full bibliographic information.
