A DOI (Digital Object Identifier) is a unique identifier that identifies digital objects. The article, paper, or object may change physical locations, but the DOI assigned to that article, paper or object will never change. Journal publishers have assigned DOIs to electronic copies of individual articles in journals that they publish. Because the DOI insures the find-ability for the journal article, object or paper, citation styles--APA, MLA, Chicago Manual of Style, Turabian, etc.--are starting to include the use of a DOI in the citation for article, paper or object.
