MDPI is a science publisher specialising in the publication of open access journals in a wide range of scientific fields.

GFZ and PIK staff receive a discount on the Article Processing Charges (APCs) for publishing in MDPI journals. This is provided by MDPIs' Institutional Open Access Program (IOAP).

The "corresponding author" must be from the GFZ or PIK and thus the respective institution must also be listed as an affiliation. Please always submit your articles with your institutional email address, as it facilitates central invoicing via the library.

What do you have to do as a "corresponding author"?

  1. Please use the institution's email address for communication with the publisher and when submitting the manuscript.
  2. When submitting the manuscript, please select your institution as affiliation:
    1. Deutsches GeoForschungsZentrum Potsdam GFZ
    2. Potsdam-Institut für Klimafolgenforschung eV
  3. You can select "Central: invoiced to institution" when submitting the manuscript. The invoice will then be sent to the library and we will contact you afterwards.

Invoicing and cost coverage

The APCs are invoiced centrally via the library within the framework of the IOAP programme. Authors are not invoiced individually for each article (exceptions see below).

At PIK and GFZ, there are internal regulations regarding the cost coverage by the sections. These are explained in more detail below.

If you have any questions, please do not hesitate to contact the staff of the Joint Library.

In consultation with the sections, the APCs are transferred to the respective Account Assignment Elements of the section budgets or third-party funded projects. Upon publication of an article, the library contacts the corresponding author or his/her secretariat and asks for notification of the cost center for further accounting.

Publications in genuine Open Access journals that can only be financed from section budget funds can be supported from the OA budget with a maximum of 1300 EUR. The remaining amount must be financed from section funds.

More information on publication costs and the Open Access publication fund and its requirements can be found on the GFZ intranet:

If the APC does not exceed the total price of 2,000 EUR (incl. taxes), your article may be funded with 20% of the costs by the Leibniz Association's Open Access Fund


If you're interested in the funding, please contact the PIK-Library (see box) as soon as possible in the submission-process.

Please note!

Any additional costs incurred are excluded from the agreement and will be invoiced individually to the authors. The additional costs must be paid by the section or from third-party funds.
