A DOI is also called a digital object identifier. It’s a number used to identify specific online articles, much like an ISBN for books. However, not all articles have a DOI number. If an article does have a DOI, it will be listed on the webpage that displays all of the bibliographic information for the article, usually called the Detailed Record page or the Abstract/Details page. It’s also usually listed within the article PDF.
DOIs can be listed as numbers like this: 10.1111/j.1540-6385.2010.00589.x
Or as a URL like this: https://doi.org/10.1111/j.1540-6385.2010.00589.x
If you cannot find a DOI on the article, this typically means it does not have one. You can also use the website http://search.crossref.org/ to find the DOI by searching the article title.
