Citation Details

Three steps

How to use the ACS citation generator

  1. Select the source type. Choose Website, Book, Journal, Newspaper, or YouTube and enter the available bibliographic information.
  2. Generate and inspect the entry. Check author initials, title, journal, year, volume, issue, pages, DOI, publisher, date, and URL wherever they apply.
  3. Use numbered superscripts. This page supports the ACS numbered system with unparenthesized superscript citations and references ordered by first mention.

Supported output

ACS numbered superscript format

ACS publications can set journal-specific requirements. This generator supports the numbered superscript system: sources form one consecutive series, and a source keeps its number when cited again. The form formats manually entered websites, books, journal articles, newspaper articles, and YouTube videos. It does not automatically retrieve records from a DOI, ISBN, or title.

  • Journal articles: enter the authors in source order, article and journal titles, year, volume, issue, pages or article number, and DOI when available.
  • Books: confirm the author or editor, title, edition, publisher, year, and relevant page range.
  • Online and media sources: check the responsible creator or organization, title, host or channel, date, URL, and access date when needed.

A well-formatted entry can still reproduce incorrect source data. Compare the result with the publisher record, especially chemical names, author initials, pagination, and identifiers.

Check the official ACS Style Quick Guide and the author instructions for your target journal before submission.

Details to review

ACS edge cases and limits

  • Repeated source: reuse its first number rather than adding the work again at the end of the list.
  • Journal abbreviations: verify the correct Chemical Abstracts Service Source Index form for a real journal title.
  • DOIs and URLs: copy identifiers from the article or publisher and check every character; the generator does not look them up.
  • Article numbers: use the supplied article number when a publication has no conventional page range.
  • Organization or no author: preserve a named organization as creator; if no creator is stated, verify the source-specific starting element.
  • Publisher variation: consult the chosen journal’s author instructions because presentation details can differ from the general ACS pattern.

FAQ

ACS citation questions

Which ACS citation system does this generator support?

It supports the numbered system with unparenthesized superscript in-text citations and a reference list ordered by first mention.

Do I reuse an ACS reference number?

Yes. When the same source appears again, cite it with the number assigned at its first mention.

How are authors separated in an ACS journal reference?

Personal authors are written surname first with initials, and semicolons separate one author from the next.

Does the ACS generator find a DOI automatically?

No. Enter the DOI or URL shown by the publisher and verify the generated reference before using it.
