Romance is only used as a brief case study, at the end of the chapter. Here's the abstract:
The empirical study of literature involves leveraging a wide range of scientific methodologies in order to better understand how literary texts are created, comprehended, and understood. This includes methods that rely on observing and measuring behavior, analyzing large corpora of texts, and sometimes manipulating some element of interest in a laboratory. Researchers engaged in the scientific study of literature have succeeded in uncovering a large number of insights regarding the role of emotion during reading. This includes the importance of emotional content in literary texts, demonstrations of the various ways that readers engage with the depictions of emotions, and a useful taxonomy of the types of emotions elicited by literary texts. We close our discussion of empirical approaches with an in-depth case study of gender and women, as both creators and consumers of literature. In doing so, we delve into women and their reading habits; the depiction of women and their emotions within literature; how and what women are perceived to read, including the phenomenon of the romance genre; and the challenges faced by women writers.
I think all of the academic works cited here about romance are in the database, with the exception of Morgan Lundy's Master's thesis, "Text Mining Contemporary Popular Fiction: Natural Language Processing-Derived Themes Across Over 1,000 New York Times Bestsellers and Genre Fiction Novels", which can be found at https://scholarcommons.sc.edu/etd/5759/
