The Museum acquired the objects either through purchase, as a gift, or in the field investigations undertaken by the Museum curators.

The department houses a great many collections, among which the most numerous are traditional ethnic garment, furniture, dishes and crafts collection.
The research results obtained by the Museum ethnologists have been regularly published in the National Museum Journal or in other specialized magazines in Serbia.
The Ethnology Department, independently or in cooperation with other museums of Serbia, organized and exposed more than thirty temporary exhibitions, which were also hosted by the museums of Serbia, as well as five permanent exhibitions hosted in Čačak and its surroundings. The following exhibitions were highly significant: Ornamentation on tombstones in 1995, Socks and nipple socks in 1996, and Fashion mirrored by sixties in 2007.
The Museum ethnologists have participated in the numerous scientific projects and organized conferences. In 2011, the Ethnology Department undertook the research, titled Childhood and Serbian cultural code, which also engaged many ethnologists from Serbia.
