I want to begin with the premise that literature is the data of literary studies. The OED tells us that the term “data,” from classical Latin, refers to “an item of information” and to “related items of (chiefly numerical) information considered collectively, typically obtained by scientific work and used for reference, analysis or calculation.” “Data” is the plural of “datum,” deriving from the Latin “dare,” which means to give.” Hence, “datum” and “data” refer not only to information but also (and more generally) to “something given or granted; something known or assumed as fact, and made the basis of reasoning.”
