Q. How do I find DOI's (Digital Object Identifiers) for sources I have used in my research?


The DOI System provides a means of persistent identification for managing information on digital networks (see https://www.doi.org).  The DOI System is implemented through registration agencies such as CrossRef, an invaluable source for looking up DOI's.  As of April 23, 2017,  CrossRef's total number of indexed DOI's was over 89,000,000 and still growing.

You can find a DOI by doing a CrossRef metadata search. You will need to  provide as much bibliographic information data as you can such as the title, author, etc.  Using the same search screen, you may also use a known DOI to find bibliographic information about an article.

The APA Style Guide to Electronic Resources provides much more information about DOI's and APA electronic references formatting with specific examples.  Important note: effective March 2017, display guidelines for CrossRef DOI's have changed. In the near future, the Johnson University Library will provide a DOI - related LibGuide tutorial for faculty and students.  We will let you know when it is published and ready for you to use.
