The documents of Soviet Supreme Command Stavka were published in the 16th Volume of the "Russkiy Arkhiv" series. The full title: "Russkiy arkhiv, Belikaya Otechestvennaya" Vol. 16 (5-1, 5-4), Terra, 1996-1999. As far as I understand it was a reissue of
the classified collection of Stavka documents published in 1968. The orders and directives of the Soviet Supreme Command published in the book cover the preparation of large-scale operations, organization of higher-level units, regrouping and transfer of forces between different fronts and between the front and the rear, some instructions of Stavka on tactical and operational questions. Aside from documents isued by Stavka the publication contains some documents of front-level, usually plans of operations submitted to Supreme command. The first two volumes also contain several records of cable conversations of Stavka and General Staff officials with fronts' commanders. Unfortunately, the publication is not full, a number of document remained unpublished, since the archive files of Stavka contain about 10 thousands various documents, it would be, of course, en enourmous task to publish them all.
