What is literary data? This chapter addresses this question by examining how the concept of data functioned during a formative moment in academic literary study around the turn of the twentieth century and again at the beginning of electronic literary computing. The chapter considers the following cases: Lucius Adelno Sherman’s Analytics of Literature (1893), the activities of the Concordance Society (c.1906–28), Lane Cooper’s A Concordance to the Poems of William Wordsworth (1911), and the work of Stephen M. Parrish c.1960. The chapter explains how the concept of literary data was used by literature scholars to signal a commitment to a certain epistemological framework that was opposed to other ways of knowing and reading in the disciplinary field.
