What is an article DOI, and why do I need it?
Because online articles may change their Web address (URL) from time to time, many scholars and style guides recommend that, when possible, you use a Digital Object Identifier (DOI) to identify an article, rather than the URL.
DOIs are an attempt to provide stable, long-lasting links for online articles. A DOI is unique to a specific document, and consists of a long code made up of numbers and letters.
