Repository access note: Selected newspaper titles cataloged by the Library of Congress with explicit county geography. Priority is given to titles beginning by 1950; up to five later titles are included where no earlier dated title is listed for that county. Dates describe publication history, not the issues available at a library. Multiple format records with the same title, place and dates are grouped. The catalog may describe paper, microfilm or online resources. Open ends and the word Current reflect the catalog description; confirm present availability and exact holdings with the libraries listed on the linked record.

Research tip

Until 1889 North and South Dakota were one territory, so early records may be filed under Dakota Territory. South Dakota took state censuses in 1895 (some counties survive), 1905, 1915, 1925, 1935 and 1945.
