The University Library Svetozar Markovic is the main library in the University of Belgrade system. 

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. The library also includes a collection of rare objects where manuscripts, old printed books, old magazines and newspapers, archival collections, as well as a collection of maps, doctoral, master's and specialist works are housed. In particular in the library's manuscript collection, there are several invaluable Cyrillic and oriental books.

The University Library in its funds has over 30 separate libraries (legacies), which are stored as separate entities. They are very different in size and importance, but they are a great value, both in terms of content, as well as testimony about the characters to whom they belonged.
