URLs stands for uniform resource locator. A URL is usually linked to a cited work retrieved online. DOIs stand for digital object identifiers which provide persistent links to the locations where the digital items can be found such as eJournals. If you have both a URL and its DOI for a work, how do you cite it in the reference list? APA Publication Manual 7th edition provides guidelines on when to include URLs and DOIs. See the guideline regarding to the scenario in which one has a URL and a DOI:
" If an online work has both a DOI and a URL, include only the DOI."
In reference list, follow this format: https://doi.org/xxxxx. For Example: https://doi.org/10.1093/aepp/ppz018.
Drop “Retrieved from” or “Accessed from” before a DOI.
