The history of Moscow's library system spans over 100 years, evolving through different political regimes. It began in the late 19th century under tsarist rule with the establishment of the first public libraries. The system grew significantly under Soviet rule, when libraries became part of the social infrastructure and were spread evenly across the city. Today, Moscow's 448 municipal libraries remain as a surviving monument of Soviet urban planning, though current issues exist as the system transitions to a new context. The libraries represent both continuity as physical presences in the city and change through their evolving functions over the past century.
