A Digital Object Identifier is a unique string of letters and numbers assigned by the International DOI Foundation. It is used to identify a digital item, such as an article on JSTOR, and to provide a stable link to its location. A DOI begins with a 10, and contains a prefix as well as a suffix. The prefix is a unique number of at least four digits that has been assigned to a specific organization. The publisher assigns the suffix. The DOI is typically located on the first page of an electronic journal article. It can also be found on the article's landing page. For more information about DOI's, see the system's homepage: http://www.doi.org/index.html.
