The present title is the second in a three-volume set addressed to the general theme of `The Soviet Union and International Cooperation in Legal Matters.' This project will concentrate essentially on the post-World War II repertory, with some reference to pre-1945 antecedents in order to put the picture in a clearer perspective. The preceding volume, published in 1988, treated the Soviet Union's record in the field of commercial arbitration and the last one in this three-volume set is scheduled to consider its related practices in the domain of criminal law. In Part II the author analyzes the ensemble of rules observed between states whereby the legal organs of one will procure for the legal organs of the other procedural services designed to facilitate performance by the recipient party of its mission to `administer justice'.
