APA 7th Edition DOI Information

How do you locate a DOI?

For journal articles, you will most often find the DOI listed on the 1st page of the article or the last page, or if you located the article through a database, hopefully you'll find the doi listed in the database

Crossref Free DOI Lookup
Try to find the DOI in Crossref. You don't have to enter all of the article information - sometimes title & date will work, other times you may need to fill in more information.
Google Scholar
Look up the article by title, and if found, click on the title to see if you're taken into the article record at the publisher's site. The article record from the publisher should list a DOI, if available.

Help, I Can't Find a DOI:

Not every online article, document, report, book, etc. has a DOI. If you've tried the above steps, and haven't found a DOI, you've done your due diligence. You can then refer to your APA Style Guide to find out how to properly cite the source when there is no DOI.
