Based on the analysis of publications of scholars and book practitioners the author formulates main features and definition of the bookselling network as a set of wholesale, wholesale-retail and retail bookselling enterprises under common management (a single management center and unified management principles), which sell the similar book and accompanying assortment of goods and services for personal and public (library) consumption to get profit. The world largest, having no analogues to date, national bookselling network was the unified state centralized system of the USSR State Printing Committee, which included 3,763 stores in 1988. After its disintegration in 1996-2000, the federal, regional and local bookselling networks started forming both in the center of Russia and in regions on other principles and in other ways. The phenomenon of the Russian book market at the turn of the XX and XXI centuries was a wholesale and retail book-selling company «Top-book» (1995-2011). The company built a system of logistics centers, developed and implemented various formats of the retail distribution network. By 2010, the «Top-Book» had over 500 stores in more than 230 Russian cities and sold above 3 million books a month. At the same time, the company's unprecedented pace of development required organizational changes: improving manageability, optimizing the budget expenditure part by reducing costs. The impossibility to solve the problems led the company to bankruptcy in 2011. The largest federal bookstore network enterprise in Russia by 2017 is the integrated retail network «Chitai-gorod» - «Bukvoed» over 528 enterprises in 167 cities of Russia. There are 55 stores in 21 cities of Siberia and the Far East. But the most significant for the regional book market is the activity of bookselling associations established in Siberia and the Far East. Mostly there are networks created by booksellers in the region, but publishing and book-selling holdings («Bichik», «Apex», «Novaya kniga», etc.) form networks to sale their own printed products as well.
