Notes on the ISSN

The BerlinUP Modellzeitschrift is for illustrative purposes only and does not represent a genuine journal. For this reason, we did not apply for an International Standard Serial Number (ISSN), which represents an obligatory persistent identifier for serial publications such as journals. The ISSN "1234-5678" given in the footer is therefore only to be understood as a placeholder.

All journals at BerlinUP Journals receive an ISSN, which can be applied for from the German National Library as the National ISSN Centre for Germany.
