During the 19th century and 20th century, a number of spelling systems for Shawnee were developed by missionaries, linguists and anthropologists. One system was devised by a Shawnee, Thomas Wildcat Alford. None of these spelling systems were widely adopted. The earliest known text in and about the Shawnee language was A Story of the Shawnee, by George Blue Jacket, which was published in Wapaughonnetta on 29 October 1829.
