The websites that make up the thematic sub-collections are selected by librarians and the sites are being archived several times per year. They typically contain websites and blogs, that is they do not contain social media that cannot be harvested by a robot, as well as online periodicals because they are kept separate. In addition to the websites of institutions, organizations and companies, the pages of professionals and artists working on that topic can also be included in the sub-collections.
The table below contains the existing and planned thematic sub-collections, and at the end we have included four genre-based selections as well: the electronic periodicals (magazines, news portals, journals, newsletters, etc.) and the collections of Facebook, Instagram, Twitter pages and podcasts, as well as the Transcarpathian sub-collection created in March 2022, which was the first geographically delimited part of the web archive.
A seed list consists from several hundred to several thousand URL addresses. We are permanently updating, expanding these lists and adding new topics to the archive every few months. Click on the abbreviations in the table to see the seed URLs. The materials of these selective collections are being stored in a closed archive in order to guarantee long-term preservation and research activities in the future. Only a small fraction of these selected websites is available through the demo collection that we have permission for public access from the copyright owner or for which no individual contract is required.
