Should I use a DOI or a URL in my citations?
Answer
Most citation styles recommend including a DOI (digital object identifier) number, if available, instead of a URL as DOI numbers can be easily used to find a source by typing them into a search engine like Google.
But a DOI number takes your reader to the website for the source, where they may not be able to access the full text.
Example DOIs:
- Traditional Format: 10.1007/s10661-022-10032-9
- Marist Library URL Format: http://dx.doi.org.marist.idm.oclc.org/10.1371/journal.pone.0028816
- URL Format: https://doi.org/10.7589/2019-01-012
All of these examples are formats that are considered correct for citation.

For sources found in library databases, it may be a better idea to provide a permanent URL to ensure your professor can access the source. Check in with them to see which they prefer.
