With numerical citations, references should be numbered sequentially. If a reference is repeated, do not give it another number; rather, use the original reference number.
With author name citations, use both names if a reference has two authors (Jones and Smith, 2002). If there are more than two authors, use the first name followed by et al. (Harris et al., 2001).
Online access to the ACS Style Guide is available via the ACS website. Chapter 14 contains the rules for how to cite references in text and create a bibliography. Some examples are provided below.
The minimum required information for a book is author or editor, book title, publisher, city of publication, and year of publication. Omit words like “Company,” “Inc.,” “Publisher,” and “Press” in publishers’ names. Some ACS publications include the chapter title in book references, while others do not. Check with the publication itself. Using the word “In” signifies the primary author(s) wrote only part of the book, not the entire book.

The minimum required information for a journal is author, abbreviated journal title, year, publication, volume number, and initial page of cited article, though complete pagination is possible. Some ACS publications include the article title while others do not. In ACS journals, capitalization follows that of the original publication; in other publications, the main words are capitalized. Check with the publication itself.
Journal abbreviation and volume are italicized. Year of publication is bolded. Use CASSI (Chemical Abstracts Service Source Index) to find standard journal abbreviations.
