Modern encyclopedia of Russian and Soviet history (MERSH) and supplementThis is designed to be the most comprehensive aid to the study of the Russian past ever created in English. It encompasses all major facts, events, personalities, and institutions important to the history of the Russian Empire, the Soviet Union, and post-Soviet Russia.
Much of the material included has not appeared in any other compendium. The Encyclopedia was compiled by translating and editing articles from many standard Russian reference sources, including encyclopedias and biographical dictionaries, supplemented by new entries by contemporary scholars.
