A Digital Object Identifier (DOI) is a unique and persistent digital identifier; it is used to permanently reference digital objects, especially scientific publications and research data. DOIs identify a specific object, rather than a current location, as a URL does.
In the case of a publication by a publisher, the DOI is usually assigned directly by the publisher. If this is not the case or you do not publish through a publisher, you can request a DOI through the library.
