Persistent Identifier (DOI, ORCID)

To reliably and permanently find, identify and cite electronically published data of any kind the data need a persistent identifier. A persistent identifier is a clear label for a digital object, it stays the same even when the name or the memory location of a publication changes.

Examples for persistent identifiers are URN (Uniform Resource Name), DOI (Digital Object Identifier), ORCID (Open Research and Contributer ID), Research ID Thomson Reuters, Scopus Author ID, GND-Number (Integrated Authority-File Number), Google Scholar Citations Profi, ISNI (International Standard Name Identifier), ISBN and ISSN.

    Digital Object Identifier (DOIs) make online publications citable.

In contrast to short-lived URL-addresses, the DOI survives as persistent identifier. The University Library assigns DOIs to digital objects (e.g. research material, essays/articles, digital reproductions, pictures) from members of the university.

Digital Object Identifiers (DOIs) help to permanently and clearly identify electronically published documents and are thus comparable to an ISBN of a book. DOIs are connected with the object and not with the memory location. In case of a changing address (URL), the meta-data will be updated and the DOI-name remains valid. This ensures that the object is permanently traceable.

DOIs are frequently used for every kind of publication and research data, and due to their broad use have become an international quasi-standard.


Every DOI-name is a unique sequence of alphanumerical characters.



The common way to cite an electronic document with DOI is as follows:

Author. Title. Publisher. Identifier

According to the decision of the university administration from June 21st 2017, the University Library functions as data center for the assignment of Digital Object Identifiers (DOIs) at the Otto-Friedrich-University of Bamberg.

The assignment of a DOI at the university is therefore carried out by the University Library.

The University Library ensures the permanent availability of the object and the meta-data as well as the quality and completeness of the meta-data.

If you have any questions regarding the DOI-assignment, please, contact opus.ub(at)

Bamberg University Library assigns DOIs to permanently published scientific documents from members of the university, e.g. articles in Open-Access-Journals, pre-prints and post-prints, congress contributions, videos, pictures, gray literature, …

Your documents are permanently published in full text on the Current Research Information System (FIS) .

We automatically assign DOIs to new electronic publications on FIS.

Upon request, it is possible to assign DOIs retroperspectively to already published documents on FIS. Please, direct your request to fis(at) and include title, author and if possible the FIS-Handle (5-digit number at the end of the URL at the front door on FIS).

In case you have any questions regarding DOI-assignment, please, contact Barbara Ziegler or  fis(at)  

   The Open Researcher and Contributer ID (ORCID) is a permanently assigned identification for

researchers. With the help of ORCIDs, registered people are explicitly linked to their publications, research data and other products of their research process regardless of name changes, spelling, institutional affiliation etc.

Publications are of great importance as part of your scientific curriculum vitae and, therefore, the citability and explicit linkage of publications, research data and other products of research processes with a specific person.

The Open Researcher and Contributer ID (ORCID) is a permanently assigned identification for researchers. ORCIDs enable an explicit assignment of research outputs regardless of name occurrence, spelling, name changes and institutional affiliation.

ORCID is run by an independent non-profit organization and is available free of charge. ORCID is used by most publishing companies and research institutes. Furthermore, it is integrated into large systems like Web of Science, CrossRef or Scopus. It is obligatory with some publishing companies and funding agencies to have an explicit identification by ORCID. Find an ORCID ID.

The registration takes place at

To register you only need your name and an email address.

Afterwards, you fill in further information and provide already available identifiers.


  • Ideally, collect all possible spellings and variants of your name, and your maiden name if applicable.
  • Grant rights to trusted parties datacite, CrossRef, Web of Science, Scopus, …, that your publications can automatically be added to your profile.

Use your ORCID.
Specify your personal ORCID in your profile, on your own homepage, in your email signature or when handing in applications. This facilitates other people’s searches for your publications and increases the visibility of your research.
