What a DOI is, and why styles prefer it
A Digital Object Identifier is a permanent ID for a published work, such as 10.1177/0956797614524581. Unlike a URL, it keeps working when a publisher redesigns its website, because doi.org always redirects to the current location. That’s why APA 7, MLA 9 and Chicago all prefer a DOI to a URL, written as a full link: https://doi.org/10.1177/0956797614524581.
This is the example above, formatted in each style:

DOI and ISBN questions
Where does the DOI data come from?
From Crossref, the registry most journals and book publishers use to register DOIs. Your browser queries it directly.
Where do I find an article’s DOI?
On the first page of the PDF (often top or bottom), on the article’s web page near the title, or by searching the title at search.crossref.org. It starts with “10.” followed by a slash.
Why is some information missing?
Crossref only has what the publisher deposited. Older records sometimes lack issue numbers or full author names, and titles may arrive in capitals. Check against the article itself.
Can I cite a book from its ISBN?
Yes. Paste the 10- or 13-digit ISBN. CiteForge checks the check digit, then looks the book up in Open Library.
