This article argues that latrinalia is an important and potentially beneficial source of public writing deserving of educators’ and researchers’ attention. I start by comprehensively reviewing the research record of latrinalia in order to demonstrate its status as a legitimate academic field while surfacing the major trends, questions, and fault lines of latrinalic scholarship. Then, after outlining how most research on latrinalia takes place on college campuses, I trace recent work on spatial practice which implicitly advocates for public discourses like latrinalia in order to make the case that bathroom graffiti is an important but often neglected source of public writing and rhetoric that aligns with contemporary conceptions of composition theory and holds pedagogic potential for the teaching of writing. Lastly, I discuss the limitations and unresolved questions of the field of latrinalia before sketching future directions for research. “The slight scratching of many of the Maeshowe Runes, and the consequent irregularity and want of precision in the forms… of what, it must be remembered, are mere graffiti.” (D. Wilson, Britanno—Roman Inscriptions: With Critical Notes, 1863)

In 1966, more than 50 scholars from the UK, US, and Canada convened at Dartmouth College to discuss the state of the profession of English teaching, ultimately proposing a “growth” model of language learning which contrasted with the skills-based models of curriculum sequencing prevalent at the time. While debates about the impact of the 1966 Dartmouth conference on the teaching of English continue to ebb and flow, from contrasting early accounts by seminar participants (Muller, 1967; Dixon, 1969) to more modern work which situates the conference as a harbinger of the process movement (Trimbur, 2008) or Writing Across the Curriculum (Palmquist et al., 2020), its continued provocation of scholarly discussion has become a legacy in its own right. Even if the Dartmouth Seminar didn't change anything happening in the classrooms of its era and thereafter, which is unlikely (Harris, 1991), it would remain a rare moment of international, professional collaboration and consideration virtually unparalleled in our field's history.
