To address the problem of changing and nonworking URL’s, scholarly publishers are assigning a Digital Object Identifier (DOI) to journal articles. The DOI is a unique and persistent link to the article.
Where is the DOI Listed on Article Citations and and Articles?
The DOI is often listed in the item record in a database, in the article citation, or on the first page of the document. It may also be found through the publisher website.
Example Citations with DOI:
