Q. How do I find a DOI for an article when it is not provided in the APA citation

Many journals do not provide DOIs for articles. When no DOI is on an article, you do not need to include it in your citation. Not every journal uses DOIs because they have to pay to register the numbers.

If it's an online source, and you don't have the DOI, go ahead and use the URL from where you found it.
