As of 2015, the Archives of Republika Srpska holds 794 fonds and 35 collections.

The archival materials span the period from the 17th century to the modern day.
The Collection of Oriental Manuscripts and Documents is the oldest holding, and it includes documents from the period of Ottoman rule over Bosnia and Herzegovina written in Ottoman Turkish.
The oldest fonds originated during Austria-Hungary's rule over Bosnia and Herzegovina.
Later fonds come from the periods of the Kingdom of Yugoslavia (1918–1941) and World War II, while most fonds cover the period of Socialist Yugoslavia (1945–1991).
Nearly half of the fonds come from government bodies and public services.
Others come from economy and banking; political organisations and citizens' associations; educational, scientific and cultural institutions; judiciary; social and health services; personal and family legacies; military bodies and institutions; and religious organisation.
The library of the Archives of Republika Srpska contains more than 20,000 items of books and periodicals, including old publications from Austria-Hungary and the Kingdom of Yugoslavia.

Twenty-four fonds and collections of the Archives of Republika Srpska were proclaimed National Monuments of Bosnia and Herzegovina in 2007.
These include the documentation of the Banja Luka District from 1878 to 1918, during Austria-Hungary's rule, and from 1919 to 1922, during the Kingdom of Serbs, Croats, and Slovenes (renamed Yugoslavia in 1929).
Also included is the documentation of the Banja Luka oblast (1922–1929) and the Vrbas Banate (1929–1941).
Four fonds contain various documents of the Independent State of Croatia, a Nazi puppet state that existed during World War II in Yugoslavia (1941–1945).
Nine fonds contain documents produced by commissions set up by the new Yugoslav authorities between 1944 and 1946 to investigate war crimes committed by the occupying forces and their domestic collaborators during World War II.
Connected to the war is also the Collection of Documents of the Central Bosnia Chetnik Corps from 1943 to 1945.
Documents of the Banja Luka District Court from 1878 to 1945 and of the Banja Luka Tobacco Factory from 1888 to the present day are gathered in their respective fonds.
Documents produced between 1946 and 1957 by agrarian commissions in the Banja Luka District are merged into a single fonds.
Included in the National Monument are also the Collection of Oriental Manuscripts and Documents from the 17th to the 20th Century, the Collection of Charts and Maps since 1807, and the Collection of Works by Veselin Masleša from 1928 to 1943 (including Masleša's original manuscripts).
