On March 26, 2010, the UT Libraries celebrated the acquisition of its three-millionth volume, the Cherokee speller Tsvlvki Sqclvclv, by D. S. Butrick and David Brown. The speller was developed by a teacher at the American Board of Commissioners for Foreign Missions’ Brainard Mission School, near Chattanooga, and a Cherokee pupil at the school, David Brown. The mission sent the authors to Knoxville to have the book produced at the printing firm of F. S. Heiskell and Hugh Brown. Six hundred copies were printed, of which only three are known to exist. The speller is more than a vocabulary builder, containing a variety of information deemed useful to the young Cherokee pupils.
