Find a DOI: Digital Object Identifiers (DOIs)
All three major citation styles (MLA, APA, and Chicago) prefer the DOI as the location information in a scholarly citation. If your source doesn't provide a DOI, try the "DOI # Finder" tool (located on the right tab) from the Alvin Sherman Library, Research, and Information Technology Center to check if one is available. Not all publications have DOIs associated with them. If the DOI is not available, follow the recommendations for the appropriate citation style on how to format the URL.
