The collection contains reports prepared for and by a variety of Soviet and Ukrainian government agencies, such as the KGB, documenting and detailing the most important developments in the wake of the explosion of the Chernobyl Nuclear Power Plant (NPP) on April 26, 1986 in the Ukrainian city of Pripyat. It also provides internal reports and investigations on the various causes of the disaster, including the problems with the design of the NPP, and the extent of the Soviet and Ukrainian government knowledge on many of the shortcomings that made the Chernobyl meltdown not only possible but in a sense inevitable.

The resource provides online access to volumes 1929-2011 of "Literaturnaya Gazeta", one of the oldest Russian newspapers focusing on topics relating to literature studies. The newspaper became the official organ of the association of Soviet authors and underwent a change of content from a pure literature organ to a newspaper covering the broader fields of literature, arts, politics and social issues. It consequently represents an outstanding source work for literature scholars on the one hand, but also for artistic-aesthetic, social, political and historical issues from Soviet times in particular. Among the official state newspapers, it can be regarded as a kind of "alternative" newspaper to "Pravda" or "Izvestia" that were completely true to party principles.
