Create citations in MLA, APA, or Chicago/Turabian formats for a wide variety of material types.
A DOI (Digital Object Identifier) is an alpha-numeric string used to provide a persistent link to electronic documents. It is similar to a book's ISBN (Interntional Standard Book Number). The DOI links the user back to the original source of publication (ejournal article or ebook). Here are two examples:
10.1080/08832320903217606
10.3748/wjg.v16.i20.2484
When available, include the DOI in your journal article references.
DOIs are not like URLs. You cannot put the DOI in a search engine and expect to find the article.
Instead, go to the DOI Resolver Site and paste it in the search box to locate your document.
