Fortunately, numerous texts from the thousands of nineteenth century Native Americans who could write have survived the passage of time. My research relies upon letters written by and for Native peoples, predominantly from the 1880s, gathered from Indian Affairs agency records at the National Archives collections in Kansas City, Denver, Oklahoma City, San Bernardino, San Francisco, and Washington D.C. Most Native-authored letters in these collections are buried in unorganized boxes of miscellaneous letters sent and received by Indian agents. Agency records from the 1880s and early 1890s were haphazardly kept and preserved, some agencies are missing wide gaps of years, and others have few surviving documents from any part of the nineteenth century. Some are preserved better than others. The Pine Ridge Agency records were well looked after, for example, but the Fort Hall and Wind River records from the 1880s and early 1890s have disappeared. The records of the Commissioner’s office in Washington D.C. were well kept and hundreds of letters from Natives were found in its boxes of letters received (which is regrettably sorted by date of arrival rather than by sender). The office received tens of thousands of letters per year (over forty thousand in 1890 alone) from agents, politicians, companies, the general public, and Native Americans.
A good number of Native texts were also found in collections from the Smithsonian's Anthropological Archives, the Huntington Library, History Colorado, the Indian Rights Association, and the Beinecke Library at Yale University. Some letters exist because of the efforts of early ethnologists and historians who managed to read, copy, or collect Native correspondence during the early twentieth century. The ethnologist James Owen Dorsey, for instance, was able to collect two hundred and thirty-eight letters written in the Native language Ȼegiha by Omaha and Ponca men and women. The letters, many of which are private correspondence, were written between 1872 and 1889. Over one hundred of those letters were published with Dorsey’s The Ȼegiha Language and the rest were published in 1891’s Omaha and Ponka Letters. These are still the largest collections of Native letter writing ever printed.
