Self-archiving Service

Kassel University Library offers you the opportunity to make a copy of your publications available online on the University of Kassel's publication server (KOBRA) and to archive them in the long term (so-called "self-archiving" or Green Open Access).

Self-archiving increases the visibility, reach and availability of your publication and is in line with the Open Access policy of the University (German only) of Kassel.


Your advantages

Your publications are published online without access barriers. They are cataloged in a search engine-friendly manner and can be found in the catalog of the UB/LMB Kassel (KARLA) as well as through scientific and commercial search services.


We assess under what conditions your publication may be published in KOBRA. Any embargo periods will be adhered to.

Publishing a copy of your publication in KOBRA may be a way to meet the Open Access publication requirements of funding bodies such as the DFG and EU.

All files in KOBRA are regularly backed up and archived for the long term. Your publication will remain accessible even if the journal ceases publication.

Not least, the COVID-19 pandemic has highlighted the importance of free access to scientific literature for teaching and research. By depositing your publications in KOBRA, you contribute to improving scientific communication and global collaboration.

Selfarchiving step-by-step

  1. 1.Report publication

    You can notify us of your publication(s) via email at We also accept lists, or you can provide us with your ORCID iD so that we can periodically or regularly check for new publications.

  2. 2.Check legal basis

    We check the legal basis on which the self-archiving can occur. This typically involves specifying an allowed version* and a timing (embargo). We're also happy to review your publishing contract, if available; in some cases, it allows self-archiving.

  3. 3.Requesting rights from the publisher

    If there is no legal basis for self-archiving, it is possible to request an individual permission from the publisher.

    We are happy to handle this publisher inquiry for you.

  4. 4.Get permitted version

    You obtain the version* that is allowed for self-archiving. This guide may assist in locating the Accepted Author Manuscript (AAM):

  5. 5.Agreement of the co-authors

    If the publication was not released under a CC license, you must obtain consent from all co-authors for self-archiving in KOBRA. When submitting to KOBRA, by agreeing to the license terms, you confirm that you have obtained this consent.

  6. 6.Upload to KOBRA

    You submit the authorized version to KOBRA. We process it for publication, complete the metadata, set up any embargo period if necessary, and then release it in KOBRA.

* = possible versions are

  • Version of Record (VoR): final version in the publisher's layout.
  • Author's Accepted Manuscript (AAM): version after peer review and corrections, but still without publisher's layout.
  • Submitted Version (SubV): the first version submitted to the publisher.
