The author of the article writes about the establishment of the National Library of Uzbekistan, which was opened in 1870. The article also contains bibliographic descriptions of published materials of various periodicals of 1920–1930 of the last century. It should be noted that published materials before 1930 were written in Arabic writing and then in later years until 1940 in latin. It is particularly noted that in 1921 part of the library passes to the old district of the city of Tashkent under the name «Eastern Library». Book funds were mainly in Russian, Arabic and Tatar, as well as in Farsi. Many works were devoted to the social development of the library, such as the replenishment of the book fund, the purchase of library equipment and technological equipment for the use of readers. And in the same year began to keep records of books on catalogue cards to find the right books.
