How to Cite a DOI
- 1. Copy the DOI.Grab it from the article's first page or the publisher's site. It looks like 10.1038/nphys1170 or https://doi.org/10.1038/nphys1170.
- 2. Paste & pick a style. Drop the DOI into the box above and choose APA, MLA, Chicago, or any of the 10,832 styles.

- What is a DOI?
- A DOI (Digital Object Identifier) is a permanent ID assigned to journal articles, datasets, and other scholarly works. It always begins with 10. followed by a prefix and suffix, such as 10.1000/182. Because it never changes, a DOI is the most reliable way to identify and cite a source.
- Where do I find the DOI of an article?
- Look on the article's first page, in the abstract or header on the publisher's website, or in the database record (PubMed, Crossref, Scopus). It is usually labelled DOI or shown as a doi.org link. You can paste either the bare DOI or the full https://doi.org/ URL — both work.
