The changes in mode of composition of William Faulkner (handwriting to typing) and Booth Tarkington (handwriting to dictation) were essentially permanent. The styles of both authors show evidence of a chronological drift, and Faulkner’s penchant for including material written much earlier into later novels further complicates his case. Taking these complications into account, multiple analyses of the novels that precede and follow the changes in mode and more fine-grained analysis of the novels in which those changes took place show that the change in mode of composition had no significant effect on either author’s style.
