The American Chemical Society (ACS) style guide is a widely used formatting style in the field of chemistry and other related sciences. When it comes to referencing sources in ACS style, accuracy and consistency are key. Here are 5 essential tips to help you master ACS referencing:
Understanding the Basics of ACS Referencing

The ACS style guide provides detailed instructions on how to format references for various types of sources, including journal articles, books, and conference proceedings. It is essential to familiarize yourself with the basic formatting rules, such as the use of title case for article titles, the inclusion of DOI numbers, and the proper punctuation and spacing.
Tip 1: Use the Correct Citation Format
In ACS style, citations are typically numbered and appear in the text as superscripts. The corresponding reference list entry should include the author’s name, article title, journal title, volume number, issue number, page range, and publication year. For example: 1. Smith, J. et al. J. Am. Chem. Soc. 2010, 132 (10), 1234–1239. It is crucial to ensure that the citation format is consistent throughout the document.
| Reference Type | ACS Citation Format |
|---|---|
| Journal Article | Author, A. A.; Author, B. B. J. Abbr. Year, Volume, Issue, pp. Page Range. |
| Book | Author, A. A.; Author, B. B. Book Title; Publisher: City, State, Year; pp. Page Range. |
| Conference Proceeding | Author, A. A.; Author, B. B. Proceedings Title; Conference Location, Year; pp. Page Range. |

Managing References with Precision

ACS referencing requires attention to detail, and it can be time-consuming to manage multiple references. Using a reference management tool, such as EndNote or Zotero, can help streamline the process and reduce errors. These tools allow you to organize your references, format them according to the ACS style, and easily insert them into your document.
Tip 2: Be Consistent in Your Referencing
Consistency is crucial in ACS referencing. Ensure that your references are formatted consistently throughout the document, including the use of punctuation, spacing, and capitalization. For example, use title case for article titles and sentence case for book titles. It is also essential to verify that the references in the text match the corresponding entries in the reference list.
Tip 3: Include All Necessary Information
When creating reference list entries, make sure to include all the necessary information. For journal articles, this includes the author’s name, article title, journal title, volume number, issue number, page range, and publication year. For books, include the author’s name, book title, publisher, city, state, year, and page range. Omitting essential information can lead to errors and inconsistencies in your referencing.
Tip 4: Use DOIs and Other Identifiers
Digital Object Identifiers (DOIs) are unique alphanumeric strings assigned to digital objects, such as articles and book chapters. Including DOIs in your references can help readers quickly locate the cited sources. Other identifiers, such as PubMed IDs and ISBNs, can also be included to provide additional information. When available, use these identifiers to enhance the accuracy and accessibility of your references.
Tip 5: Double-Check Your References
Finally, it is essential to double-check your references for accuracy and consistency. Verify that the references in the text match the corresponding entries in the reference list, and ensure that all necessary information is included. Use a reference management tool or consult the official ACS style guide to help you identify and correct any errors. By taking the time to carefully review your references, you can ensure that your document is well-formatted and free of errors.

What is the difference between a DOI and a PubMed ID?
+A DOI (Digital Object Identifier) is a unique alphanumeric string assigned to a digital object, such as an article or book chapter. A PubMed ID, on the other hand, is a unique identifier assigned to a citation in the PubMed database. While both identifiers can be used to locate cited sources, they serve different purposes and are used in different contexts.

+To format a reference for a book chapter in ACS style, include the author’s name, chapter title, book title, editor’s name, publisher, city, state, year, and page range. For example: Author, A. A.; Author, B. B. Chapter Title. In Book Title; Editor, E. E., Ed.; Publisher: City, State, Year; pp. Page Range.
What is the purpose of using a reference management tool?
+A reference management tool, such as EndNote or Zotero, helps you organize and format your references according to the ACS style. These tools can also assist you in inserting references into your document and verifying that the references in the text match the corresponding entries in the reference list.
