An article's DOI (document object identifier) is like an electronic thumbprint that allows you to find an article even when it changes its Web address.
It can usually be found on the first page of the article. It looks something like https://dx.doi.org/10.5195/palrap.2016.130 or https://dx.doi.org/10.1016/j.bbagrm.2016.08.009.
Not all articles have a DOI, if yours doesn't:
- For MLA citation, include the website address and date you accessed it.
- For APA citation, include the publication's homepage URL.
