These kind of sub-collections are being setup focusing on main national or global events. The materials of these collections are based on selected articles/sections of main news portals, websites of corresponding institutions, thematic homepages, blogs, Wikipedia articles etc. Harvests are usually starting some weeks before the main event (if we know the exact date of an event) and ending when the press coverage of the event is mainly disappearing. Making a weekly harvest is usual from the enlisted websites. The spreadsheet below contains the already existing or planned sub-collections of the archive by the status of early 2020. Click on the abbreviations to see the selected and archived URL addresses.
The materials of these sub-collections are being stored in a closed archive except the Rákóczi and the Széchényi archives because for selected websites/webpages we have permission for public service from the copyright owners.
