Open Access
This journal is exclusively publishing gold open access since 2014. This means that the journal publishes peer-reviewed articles as first publications and guaranties access without significant technical and legal hurdles, making all content freely accessible and reusable.
The journal platform provides free access to the current issue and to all volumes published since 2014 (vol. 16). Print editions from volumes 1 to 15 are gradually being uploaded and will also be made available as an Open Access archive in the future.
