“The Repertorium is an extraordinary achievement, one of the most substantial contributions to ME prose studies ever.” (Prof. A.S.G. Edwards, De Montfort University, Leicester)
"The SERMO project to publish catalogues of medieval European vernacular sermons, of which these Middle English volumes are part, is both a major contribution and a tool which will expedite further work. It is a massive undertaking: these four volumes catalogue 1,481 texts of sermons (the longest of 121 folios) in 162 manuscripts."
"Aiming to present the genre in its widest range, O'Mara and Paul reviewed an impressive number of texts (1481 sermons in 162 manuscripts), collected from mainly British libraries and a few North American ones, to present an amply indexed tool which no doubt will become indispensable to all students of Middle English preaching material. In other words, a dream come true." (L. Iseppi, in: The Medieval Review, 09.03.19)
