"A Potent Lever for Social Progress": The Imperial Public Library in the Era of the Great Reforms

Although underway before and continuing well beyond the 1860s, the democratization of Russian intellectual life was one of the most consequential of the dramatic social and political changes that took place in Russia in the 1860s. For the Imperial Public Library in St. Petersburg, these changes presented a forceful challenge to respond to the needs of a vast influx of new readers. Although the library staff had divided opinions on the mission of the library, there was considerable support for reform from within, and the changes in organization and operations introduced in the 1860s reflected a strong willingness to adapt to changing social conditions. As a result, the library was increasingly regarded by educated society as a vital tool for social and scientific progress. Today, as the Saltykov-Shchedrin State Public Library in Leningrad, it remains one of the world's two or three largest libraries.
