Note

These reports are tagged on the two websites, in the entries for ‘Estonian SSR’ in “Guided Search” and ЭССР in “Tags”, respectively, in the right-hand column of the page. They include, for example, the 1969 case of the Baltic Fleet officers and 1983 arrests in Voronezh (Central Russia).

If links from such reports do not identify shorter items on the same topics, a general search will turn up more mentions of individuals and events in the “News in Brief” section of the Chronicle and the оther shorter fortnightly entries in «Вести из СССР».
