Vol. 1 No. 3 (2021): Grey Issue

In this issue of our Modellzeitschrift BerlinUP, articles that have already been published on the subject of Open Access journals are republished. This provides a thematic introduction for publishers as well as a practical example for a so-called overlay journal. Overlay journals do not generate their own content, but rather curate open access content that is already freely accessible and reusable.
