This paper examines the formation of various series of university registers belonging to the genre of pragmatic literature. The university was a complex entity—a corporation of corporations—combining hierarchy and collegiality with significant autonomy, drawing on both ecclesiastical and secular models. The institution’s financial support was based on direct revenues—including fees from students and graduates—as well as grants and endowments from secular, ecclesiastical, municipal authorities, and private individuals. How did the registers reflect the development of the institution and address the evolving needs for documenting successive aspects of the university’s operations and its affiliated institutions? How can the typology of these registers be characterized? The presentation also explores attempts to establish uniform chancellery rules within various university institutions, along with the influence of customary practices and collective memory on the documented content.
