GGC's Academic Enhancement Center (AEC) can help with all your citation needs!
If the Digital Object Identifier, (DOI) is not listed, it might be found via a DOI locator.
If the DOI is longer than you prefer, try the doi and url shortner.
Basic rules and preferred link options for digital content:
If the source has a doi, use the doi.
If the source does not have a doi, use the permalink.
If the source has neither a doi or a permalink, use the url.
