Citing Your Sources in ACS Style

How to cite in ACS style

• Use an in-text citation to acknowledge that you are quoting or paraphrasing another author's words, ideas or data in the text of your research paper.
• Choose one of the following methods for citing references in-text:
  • Add a superscript number at the end of the text being cited
  • Use an italic number in parentheses at the end of the text being cited
  • ​Put author’s name and resource publication date in parentheses at the end of the text being cited
  • Include a reference list at the end of your paper. The list should begin on a new page and contain a full citation for each in-text citation referenced within your paper.
  • Each full citation should include the specific publication information required by the American Chemical Society rules. This allows your reader to find the sources, if desired.
  • If you used superscript or italic numbers for your in-text citations, arrange your reference list in numerical order.
  • If you used author's name and date for your in-text citations, arrange your reference list alphabetically by the last name of the author.
