Southwest Texas State University (James Barton, Luann Brunson, Bob Hardesty), undated

Personal correspondence in this subseries includes letters to Vliet from long-time friends such as Ruth Bloom, Harry Clauss, Alan Distler, John Haag, Ralph Houston, and David Lyttle. Several letters from Vliet to Ralph Houston are also included here, presumably sent to Ann Vliet after R.G. Vliet’s death. These letters are of special interest in that they discuss Vliet’s writing and his health. Correspondence from Vliet’s family include genealogical information, and a letter from Vliet’s father, R.G. Vliet, Sr., regarding the use of the name “R.G. Vliet” in published materials.
