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).
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.

This citation, below, is in ACS format. The journal shown in this example has a volume number but not an issue number. If there is an issue number, it is found after the volume number, but before the page number(s).

Note: Journal abbreviation and volume are italicized. However, issue number (if present) is not italicized. Year of publication is bolded. Use CASSI (Chemical Abstracts Service Source Index) to find standard journal abbreviations. Here is an example, below, of an article with an issue number.
