I have had some success locating some smaller and limited run Missouri newspapers at Chronicling America. The Sedalia Bazoo was the most exciting find. The paper ran as a daily 1886-1881, and a weekly thereafter through 1904. The October 22, 1889 Sedalia Weekly Bazoo carried the story of my great great uncle's death with details I had yet to find anywhere else.
Chronicling America is a great resource, not only of digitized pages but also of determining where current copies of newspapers might be found on microfilm and original hard copy. Here is the Sedalia Bazoo page that shows locations and the approximate date ranges for the paper.
