Q. How do I find DOI numbers?

Answer

Articles may or may not have DOI numbers assigned to them as the DOI system is a fairly recent concept. Articles published prior to 2000 are less likely to have DOIs.

You can locate a DOI by 1) looking at an article’s record in one of our Library’s databases; 2) looking at an article itself (hard copy version or electronic; 3) using a free DOI lookup called Crossref.

If looking at article records in our Library’s databases, be aware that ProQuest does not include ANY DOI information. Some articles in Roadrunner Search and EBSCOhost databases do have DOIs. If they do, you can find this on the article record page (click on the article title from the search results screen to get to the record page).

In Roadrunner Search:





Another way to locate a DOI is to look at the article itself, either a hard copy or electronic version. In best publishing practices, the DOI should be listed prominently on the first page of an article, whether in print or online.





Lastly, you can try locating a DOI using CrossRef, the free DOI lookup. CrossRef searches for DOIs using information such as article title, authors, and publisher information. Or cut and paste your entire reference list into the Simple Text Query form and CrossRef will return all available DOIs at once.

If you cannot locate a DOI and you are unsure how to proceed please see our FAQ on No DOI.
