Open Access Policy

Open Access and Self-Archiving Policy

The journal Challenges of the Future provides open access to all published scholarly articles in accordance with the principles of open science. All articles are freely available without subscription or payment, for both individual users and their institutions. In doing so, the journal promotes broad accessibility of research outputs and supports the global exchange of knowledge.

Users are permitted to read, download, copy, distribute, print, search, or link to the full texts of articles for any lawful purpose without prior permission from the publisher or the author. This approach is consistent with open access principles.

Open Access

The journal operates under the diamond open access model, meaning that no fees are charged to authors (no APCs) or readers.

Copyright and Licensing

This license permits:

  • sharing (copying and redistributing the material in any medium or format)
  • adaptation (remixing, transforming, and building upon the material for any purpose, including commercial use)

under the following conditions:

  • appropriate attribution must be given
  • the original publication in the journal Challenges of the Future must be cited
  • any derivative works must be distributed under the same license

Self-Archiving

The journal allows authors to archive all versions of their manuscripts:

  • preprint (before peer review): may be archived without restrictions
  • postprint (after peer review): may be archived in institutional and subject repositories
  • final published version (publisher PDF): may be archived

Final published versions of articles (PDF) are also permanently deposited in the ReVIS repository.

When archiving, authors are encouraged to:

  • include full bibliographic information
  • provide the DOI (if available)
  • include a link to the original publication in the journal Challenges of the Future

Embargo

The journal does not apply any embargo. All versions of articles may be archived immediately upon publication.
