Vsya Moskva (literally translated "All Moscow" or "The Entire Moscow") was a series of city directories of Moscow, Russia, published on a yearly basis from 1872 to 1936 by Aleksei Sergeevich Suvorin. The directories contained detailed lists of private residents, names of streets and squares across the city with the details of their occupants and owners, government offices, public services and medium and large businesses present in the city. Each volume was anywhere between 500 and 1500 pages long. They are often used by genealogists for family research in pre-revolutionary Russia and the early Soviet period when vital records are missing or prove difficult to find. Historians use them to research the social histories of the city. Source: Wikipedia (en)
