Identifiers for Publications.

DOI Allocation

A DOI (Digital Object Identifier) is a permanent, digital identifier for digital objects. Mainly used for scientific online journal articles, having a DOI makes it easier to cite and find your work. DOIs can, however, also be allocated to other types of document or research data.

Similar to an ISBN, a DOI is assigned only once to each document and remains permanently linked to that DOI. The object can be retrieved at any time using a DOI resolver, regardless of the actual server address. The DOI does not lead directly to the object, but to the so-called landing page of the object and its metadata.

If you need a DOI, please contact the Competence Center for Bibliometrics and Publication Support by sending an e-mail to:
