The documents used in the collection were transferred by the Center for the Storage of Contemporary Documentation (Moscow) to the Cummings Center for the Study of Russia and Eastern Europe (Tel Aviv University) in accordance with the agreement between the parties dated May 23, 1995. The time frame of the collection covers the period from 1957 to 1989, although the bulk of the documents fall on the late 60s - early 80s. It is based on documents that have been postponed as a result of the work of the highest party bodies and are currently in the Center for the Storage of Modern Documentation (CCHSD). At the same time, there are also materials from the State Archive of the Russian Federation (GARF), the Foreign Policy Archive of the Russian Foreign Ministry and some others in the collection.
