Q. I cannot locate a DOI for my electronic source. What should I do?


Although most major journal publishers now provide DOIs for articles published in their journals, not all articles will have assigned DOIs. This is the case for older print articles and articles from journals which do not yet not use DOIs. If you are unable to locate a DOI using the NCU Library Databases or CrossRef.org, then your article likely does not have an assigned DOI. However, you will want to make sure that you have checked the article itself and the database record, in addition to CrossRef. The following video from the APA Style Blog demonstrates how to do so:


If you cannot find a DOI for an online article, cite the URL for the journal's homepage, as stated on pages 191-192 of the Publication Manual of the American Psychological Association 6th Edition. This will require you to do a Google Search in order to locate the journal’s home page. If you are not able to find a homepage for a particular publication, according to APA's DOI And URL Flowchart you have the choice to cite the database name and include the accession number for the article/publication you are citing.

Please note that this information only serves as guidance. If your professor has requested additional information to be included in your APA references (such as persistent URLs), please abide by their requirements. Contact your professor for clarification.
