The Nebojša Popov Collection is held at the Historical Archives of Belgrade in Serbia. Nebojša Popov, a sociologist and intellectual, became one of the most renowned antiwar activists in Serbia and former Yugoslavia and was known for his involvement in various intellectual, academic, and political activities critical of contemporary authorities. From 1975 to 1981, Popov's work was deemed politically unsuitable so that he was excluded from academic institutions. This collection contains manuscripts, press clippings, court decisions, appeals, minutes of opposition meetings and round table discussions, book excerpts, articles from academic journals, and about three-hundred books from Popov's private library.
