This article describes an attempt at introducing the quantitative perspective available through corpus stylistics into the discussion regarding Hemingway's linguistic development throughout his career. By building a corpus of Hemingway's fiction, previous statements and research into the author's style are explored through part-of-speech tagging and diachronic presentations of data regarding word class distributions, sentence lengths, and lexical density. This method combines literary theory with contemporary advances in digital humanities to offer a nuanced investigation of underlying text patterns that are otherwise frequently overlooked.
