How to use the ACS citation generator
Choose a source type, paste a DOI, URL, patent number, or title if you have one, then complete the manual fields. Select superscript numbers, italic numbers in parentheses, or author-date before copying the reference.
ACS website citation format
ACS website citations should identify the author or organization, page title, website name, URL, and access date. Access dates matter because web pages can change.

What to check before submitting
Confirm author order, spelling, year, journal abbreviation, patent country, DOI URL, and access date before you paste the citation into a paper. ACS assignments and journals can vary, so use the required course or journal instructions as the final authority.
ACS in-text citation styles
ACS supports numbered citations as superscript numbers, numbered citations as italic numbers in parentheses, and author-date citations. Follow your instructor, journal, or department requirement.
Citation data and limitations
DOI lookup uses public Crossref metadata when available. Patent, website, book, thesis, and conference fields still need human review because public records may use different title casing, assignee names, abbreviations, or publication dates.
Common ACS citation mistakes
- Using only the home page URL instead of the exact page consulted.
- Leaving out the access date for a changing web source.
- Treating a PDF report as a generic web page when it has a report author or publisher.
