Aggregate data of the bulk harvests in 2024
    • The web archiving project has started at the beginning of 2017 in the HNMPCC National Széchényi Library,
      the test period lasted until 2019.
    • The aim is to preserve and make searchable documents and information sources produced and distributed in digital form.
    • The primary scope of collection is scientific, cultural, educational, and public sphere web content.
    • Types of archiving:
      – periodic harvests of selected Hungarian websites (by theme, genre, institution);
      – events related harvests (news portal sections, relevant websites and blogs);
      – snapshots of the Hungarian web space (servers under the .hu domain and other Hungarian related content);
      – individual backups of content shared publicly on social media (primarily pages/channels of institutions and organizations, in small quantities, for testing purposes).
