The University Library Svetozar Marković (Serbian: Универзитетска библиотека Светозар Марковић) is the main library in the University of Belgrade system, named after Svetozar Marković, a Serbian political activist in the 19th century.

The library holdings include seminal works from all scientific fields, a large collection of local and foreign encyclopedias, bibliographies, dictionaries, professional and scientific journals, university publications, textbooks, and a significant collection of doctoral dissertations.

Its funds were made up of gifts from local and foreign donors, and a sample copy of the Principality of Serbia.

According to the provisions for establishing the Lyceum, the librarian had to be one of its teachers, the first of which was Dr. Janko Šafarik (1814–1876), philologist and professor of history.

Soon it was realized that the university required a general scientific library, but the outbreak of World War I delayed its establishment.

Shortly thereafter, in May 1921, professor Uros Džonić was appointed trustee of the University Library, who was temporarily given an office at the Faculty of Philosophy.

On the initiative of Serbian delegates in Washington, D.C., Dr. Slavko Grujić, Carnegie Endowment for International Peace, who had already built a series of libraries in the world, approved a $100,000 gift to the Serbian government to build and equip a library in Belgrade.

The city of Belgrade donated land, and the project was designed by university professors, architects Dragutin Đordjević and Nikola Nestorović.

The main task of this institution was that "as an independent university institution helps cultivate the science and in the capacity of research libraries serve not only students and faculty of Belgrade University, but also to all those involved in science."

In the period after the Second World War began the application of modern methods in the organization and processing of funds.

Organized by the Library, in collaboration with other institutions of the University of Belgrade, has been held for more than 20 of these lectures via video link or live, with speakers from the EU, the US and the region.

The first group training were within the TEMPUS project, the target population consisted of academic librarians in the organization of the Community of Libraries of the University of Serbia.

What was formerly called the reference links are in a much clearer, more organized, meaningful and attractive way to achieve this library guides.

For each scientific discipline, in addition to texts, images, video recordings, are available and useful links to associations, conferences and other current information.

The purpose of local interlibrary loan identified primarily in meeting the demands and needs of the user – library, both for information and for their sources in different fields of science, culture and art.

In addition, it is necessary to understand the needs and structure of the user to be in line with the dynamics of providing information, which again must be the result of more efficient activities of the department that deals with interlibrary loans.

Changes in the expectations, requirements and user type affected the interlibrary loan in the University Library "Svetozar Marković", which represents the connection between classical or physical and digital lending, reflecting both the dual nature of the modern library.

Library of Dimitrije Mirtinović, who lived and died in London, contains literature in philosophy, ethnology, anthropology, and Oriental art.
