Open Access

This journal is exclusively publishing gold open access since 2024. 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 2024 (vol. 24). Previous volumes (vol. 1-23) and their articles are archived on an alternative platform and are linked within this journal. They are freely available, but not published according to the journal's current open access policy.

License

From volume 24 onwards
All articles from vol. 24 on are published under the Creative Commons Attribution 4.0 International (CC BY 4.0) license. This license allows third parties to redistribute, modify and combine articles with other works, including for commercially purposes, as long as the author of the original is named. The CC BY license thus significantly promotes the visibility and reach of publications and allows legally scure and free use, also in combination with other CC-licensed works.

Volumes 1-23
Volumes 1-23 from the years 2008-2023 were published on an alternative platform, under a different license.

Copyright

It is the responsibility of the authors to obtain all necessary copyright permissions for the use of third party materials in their publications.

Self-Archiving

Authors are permitted to deposit their articles in all versions of the publication process in an institutional or subject repository, as well as on their personal or institutional homepages. This includes preprints, author's accepted manuscripts as well as published articles (version of record).

After successful publication authors should provide a link from the deposited version to the version of record on the journal's website using the article's digital object identifier (DOI).

By self-archiving their publications, the authors support and promote open access as well as the outreach of their research.
