Digital archiving and preservation

1. General Principles

The journal ensures long-term preservation and accessibility of all published materials in accordance with international standards for digital archiving, LOCKSS/CLOCKSS principles, and COPE best practices. The archiving strategy guarantees preservation of the scholarly record regardless of hosting or administrative changes.

2. Online Archiving on Hosting Servers

All published articles, issues, metadata, and supplementary files are stored on secure hosting servers with automated daily and weekly backups to prevent data loss, corruption, or unauthorized access.

3. Offline Storage on Solid-State Drives (SSD)

To enhance long-term preservation, the journal maintains offline archives stored on solid-state drives (SSD) outside the online environment. These archives include:

  • full issues (PDF),
  • published articles,
  • publication metadata,
  • editorial documents,
  • submission & review histories (as allowed by COPE).

4. LOCKSS Publisher Manifest

The journal supports the LOCKSS (Lots of Copies Keep Stuff Safe) system.
The LOCKSS Publisher Manifest enables libraries to collect, preserve, and serve authentic copies of the journal’s content through trusted, independent networks.

5. CLOCKSS Publisher Manifest

The journal also supports CLOCKSS (Controlled LOCKSS).
The CLOCKSS Publisher Manifest ensures decentralized, controlled preservation and guarantees open access to the journal’s materials if the content becomes unavailable online.

6. Redundant Physical Storage

Duplicate archived copies are stored at a separate physical location to ensure recovery in case of force majeure or catastrophic failure.

7. National Archiving (Ukraine)

Additionally, all journal files, including full issues and individual published articles, are periodically archived and preserved at the Vernadsky National Library of Ukraine (Kyiv), ensuring long-term preservation in line with national standards.

8. External Indexing & Preservation Services

The journal’s metadata are also preserved in external indexing services (Crossref, Google Scholar, national repositories), providing an additional layer of redundancy.

9. Open Access to Archived Content

All archived materials remain openly accessible. If the journal ceases publication, the archive will be preserved and remain available to users.
