IEEE prints author initials before the surname and abbreviates the periodical title. Check the abbreviation for Proceedings of the National Academy of Sciences against your target publication's reference list before submitting.

APA puts the year directly after the authors, keeps the full journal title in italics, and renders the DOI as a URL.
BibTeX

}The citation key is the first author's surname and the year. Keep it stable once it appears in a draft, because renaming it breaks every cite that used it.
What to verify before you submit
- The volume and page range. Proceedings of the National Academy of Sciences records 172,909 works, and articles published online first can carry a different volume from the final issue. Cite the version you read.
- The abbreviated title. IEEE style uses standard periodical abbreviations, and registry metadata almost always returns the full name instead.
- Author name order. Registry records store full given names; IEEE and APA both want initials, formatted differently from each other.
- Whether the article is open access. This journal is not fully open access, which affects whether a reader can reach the version you cited.
- That the source supports your claim. A correctly formatted reference says nothing about whether the passage backs the sentence citing it.

Questions about Proceedings of the National Academy of Sciences
What is the ISSN of Proceedings of the National Academy of Sciences?
The linking ISSN is 0027-8424. The journal also carries 1091-6490, which usually separate the print and electronic editions. Use the linking ISSN in a BibTeX issn field.
Who publishes Proceedings of the National Academy of Sciences?
National Academy of Sciences publishes it. Check the journal's own author guidance rather than a general publisher template, because reference style is set per title.
Is Proceedings of the National Academy of Sciences open access?
OpenAlex does not record it as fully open access. Some articles may still be open individually, so check the specific article rather than assuming from the journal.
How do I cite an article from Proceedings of the National Academy of Sciences in LaTeX?
Use the BibTeX entry above as the pattern. The entry type is article, the journal field holds the full title, and the citation key sanger1977 follows the first author's surname and the year. Brace any acronym in the title so your bibliography style does not lowercase it.
Does Proceedings of the National Academy of Sciences use page numbers or article numbers?
The example article runs from page 5463 to 5467, so this journal used page ranges at least for that volume. Newer issues in many journals switched to article numbers, so check the version you are citing.
How influential is Proceedings of the National Academy of Sciences?
Its h-index is 1,178, above 99% of the journals covered here, and its articles have been cited 23,042,963 times in total. Its two-year mean citedness is 8.52. These are indexing figures, not a judgement of whether a specific article is sound.
Does Proceedings of the National Academy of Sciences have a Journal Impact Factor?
Not one shown here. The Journal Impact Factor is Clarivate's metric, published in Journal Citation Reports and readable only with a JCR subscription, so this page does not restate it. The figures above come from OpenAlex: an h-index of 1,178 and a two-year mean citedness of 8.52 across 172,909 indexed works, captured on 2026-09-18. Mean citedness averages citations per work over a two-year window, which makes it closer in construction to CiteScore than to the Impact Factor. The three are not interchangeable, so quote whichever one your target venue actually asks for.
