In January 2020, a new digital-first edition of the ACS Guide to Scholarly Communication was released. SFU Library does not have access to the 2020 online edition at this time. Although the new edition has been updated and expanded with new chapters, the basics of ACS Citation remain the same. Please refer to the Quick Style Guide document below for examples.
A DOI is a unique alphanumeric string that identifies an article and provides a stable link to its location in cyberspace. DOIs may be found on the first page of a downloaded article. Look for a number that starts with a "10" like in these examples:
10.1037/0278-6188.8.131.529 or https://doi.org/10.1037/0278-6184.108.40.2069 or http://dx.doi.org10.1037/0278-6220.127.116.119
Include a DOI for all works that have a DOI, regardless of whether you used the print or online version.
If an online work has a DOI and a URL, include only the DOI.
Regardless of the format that you find the DOI listed, provide it in the preferred format ... https://doi.org/10.XXXX/aXXXXXXX
If your article does not have a doi, use crossref.org
Choose Search Metadata and paste your article title.
A URL (Uniform Resource Locator) specifies the location of digital information on the internet and can be found in the address bar of your Internet browser. document and file name. Use a URL in citations for websites, not for articles except when you cannot determine the DOI from the document itself or after searching crossref.org.
