Digital object identifier (DOI) is a unique alphanumeric string assigned by a registration agency (the International DOI Foundation) to identify content and provide a persistent link to its location on the Web. The publisher assigns a DOI when an article is published and made available electronically. The DOI is unique to each individual work. More information about DOI's can be found in this FAQ response.
