Open access policy and terms of use for copyrighted materials

6.1. Open Access Model

The Bulletin adheres to a policy of immediate open access to all published materials. The full texts of all articles are freely available to readers in HTML and PDF formats on the Bulletin’s official website from the date of publication.

The Bulletin supports the principles of the Budapest Open Access Initiative (BOAI) and strives for the widest possible dissemination of scientific knowledge.

6.2. No publication fees

The Bulletin does not charge article processing charges (APCs) to either authors or their institutions. Submission and publication in the Bulletin are completely free of charge for authors. Students in state-funded third-cycle higher education programmes are also exempt from any charges, in accordance with sub-clause 6 of clause 7 of the Ministry of Education and Science Regulations.

6.3. Licence

All articles are published under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0) licence. This licence permits:

  • free distribution and adaptation of materials, provided that authorship and the original publication are acknowledged;
  • non-commercial use of materials only;
  • distribution of derivative works only under the terms of the same licence.

6.4. Copyright

Authors retain copyright in their works without restriction and grant the Bulletin the right of first publication. Authors have the right to:

  • deposit the published version of the article in institutional or subject-specific repositories and on personal websites;
  • include the article in books or monographs (with attribution to the original publication);
  • use the article for teaching and research purposes;
  • deposit the Author’s Accepted Manuscript (AAM) in open repositories (in particular, the institutional repository of NTU ‘KhPI’, DOAJ, etc.).

6.5. Self-archiving

The Bulletin supports self-archiving and allows authors to deposit their articles or accepted manuscripts (AAMs) in institutional or subject-specific repositories without an embargo. Authors are encouraged to deposit their work in open repositories, as this increases the citation rate and visibility of their work.
