Archiving and long-term storage policy

The journal ensures the archiving and long-term digital storage of all published materials, providing free access based on the principles of open access and academic integrity.

Archiving and placement in repositories

Journal materials are archived by:

• placing electronic versions of articles in the Archives section on the official website of the journal;
• placing publications in the electronic archive of the V. I. Vernadsky National Library of Ukraine of the NAS of Ukraine
• allowing authors to self-archive the final version of articles in open scientific repositories, provided the bibliographic reference to the original source is preserved.

Technical means

To ensure long-term storage and data protection, the editorial office uses the following:

• regular backup of the electronic archive;
• storing materials in standardised formats (PDF, HTML), which are suitable for long-term use;
• permanent unique identifiers (DOIs) for each publication.

Accessibility Guarantees

Measures are taken by the editorial board to guarantee continuous access to archival materials, even in the event of changes to the technical infrastructure or cessation of the journal website's operation. This is achieved by storing materials in external open-access repositories.
