The Belarusian State University Fundamental Library (BSU FL) was founded on May 23, 1921.

BSU FL is one of the oldest and biggest university libraries in the Republic of Belarus. 40 thousand books given by the People’s Commissariat for Enlightenment of the BSSR as well as additional 20 thousand books from the former Theological Seminary became the basis of its funds. In total the initial contributions of local stocks in the BSU FL funds was about 70 thousand volumes.

In 1922 in accordance with the BSSR Council of People’s Commissars’ decree the BSU FL was transformed into the Belarusian State and University Library, which combined functions of the state library with functions of the university library. As the library also performed functions of the central bibliographical institution in BSSR, the Belarusian Book Chamber (in 1924) and the Bibliographic Bureau (in 1925) were created at the library.

For many decades, the BSU Fundamental Library has been the coordinating and methodological center of the library network of institutions of higher education in the Republic of Belarus (49 libraries).

Today, the BSU Fundamental Library consists of more than 1.6 million volumes of the universal fund of Russian and foreign literature; more than 27 thousand users; about 1.5 million book issues and access to electronic information resources (electronic catalog, Electronic library and licensed databases).
