Digital Object Identifier (DOI)

Since 2000 there has been an effort to assign everything that exists in the digital world such as online articles with a unique number called a Digital Object Identifier or a DOI.  The DOI is unique, permanent, and persistent. It remains the same despite changes in URL's or permanent removal from the Internet. If no DOI is present, try the free DOI lookup from CrossRef.

For more information, watch the short video, Citing an article with a DOI and without a DOI (University of Maryland University College). If you have questions, Webster students, faculty and staff should contact the Webster U. Library Reference Department (info in the Help box).

How do I cite articles from the library's databases?

When you cite a full text article retrieved from a Webster University Libraries database, some citation styles require you to cite the database name and/or a URL. Here’s how the University's most-used citation styles address this issue:

  • APA (7th): Include only the Digital Object Identifier (DOI) if it is available. If there is no DOI listed in the database or on the article itself, do not include any database information or a URL.
  • MLA (9th), Chicago, AMA, Harvard: If a DOI is present, add both it and the database name to the citation. If a DOI is not present, include the database name and provide the database permalink or URL (if there is no permalink).

Be sure to check the citation guide for how to format the citation required for your assignment.
