The U.S. Ambassador’s Fund for Cultural Preservation (AFCP) invested $106,000 in this project, which aimed to repair the leaking roof and damaged facades of the main building of the University library “Svetozar Markovic”. The repair of these damaged areas prevented further destruction of the library’s structure and consequently reduced the possibility of losing its priceless old and rare books, manuscripts and maps. The collection of the University Library consists of monographs, periodicals, manuals, manuscripts, archival material, doctoral dissertations and electronic sources. In addition, invaluable special collections and legacies (27 in total) among which is the Carnegie collection, which was donated to the University Library in 1927, are stored in the building. The building suffered serious damage due to rainfall and subsequent water penetration, as a result of which the roof was corroded and full of bad joints, and the facade was significantly damaged. Dampness in the rooms created mold and jeopardized the condition of numerous valuable collections such as legacy collections from famous Serbian scientists and writers, archival records containing documents from the 17th to 20th centuries, 15 incunabula from the 15th century, portions of manuscripts dating from the 13th century and over 10,000 additional old and rare books and manuscripts. The project was successfully finished in 2017.
