Notes from CPSU Politburo meetings and many other high-level discussions from 1985 to 1991 were gathered in 2003–2004 by the Gorbachev Foundation for transcription in a planned six-volume document collection titled "Kak delalas politika perestroiki" (henceforth referred to as "KDPP") that originally was scheduled to appear in 2004. Unfortunately, Gorbachev decided not to publish the volumes, which would have come to more than 3,500 pages in total. Later on, he did permit a much abridged single volume to appear (Chernyaev et al. 2006), as well as a collection of documents pertaining to Soviet policy in Germany (Galkin & Chernyaev 2006). In 2010, another thick volume was published with notes and materials (including some already publicly available) from Gorbachev's meetings and conversations with foreign leaders (Chernyaev & Veber 2010), but the other documents planned for KDPP have not yet been made generally available. Fortunately, Anatolii Chernyaev, who oversaw the project and would have preferred to release all of the materials, agreed to give me (and other researchers) access to the unpublished volumes when I was in Moscow numerous times from 2005 to 2009. I am grateful to Chernyaev for the opportunity to examine all of the documents.
