Print copies of the 3rd edition of the ACS Style Guide can be found in several libraries on campus. Online access is also available via the ACS website. Chapter 14 contains the rules for how to cite references in text and create a bibliography. A short summary of those rules and some examples are provided below – note these only scratch the surface of the style rules. Consult Chapter 14 for more detailed citation issues.
In Text Citation
References in the text should be cited in one of three ways:
- by an italic number
- or by superscript number
- or by author name and date
References should be numbered sequentially. If a reference is cited more than once, it does not receive a new number. If citing more than one reference at a time, include reference numbers in increasing order separated by commas.
Italic Number Example: …preparing N-(p-nitroaryl)amides (2).
Author Name and Date Example: …preparing N-(p-nitroaryl)amides (Stern and Cheng, 1995).
The bibliography, or reference list, appears at the end of the paper in alphabetical order if cited by author and date or in numerical order if cited by numbers. Different reference formats (book vs. journal vs. website) have different rules for citation. See below for some common format examples.
Books and Book Chapters
NOTE: 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.

NOTE: 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. If you find the article online, put [Online] after the journal name, but do not include the URL.

NOTE: The minimum required information for a website is the site title, URL, and date accessed. Include the author name if one is listed. Add “Home Page” to website titles as needed.
