Follett, Westley, “Religious texts in the Mac Aodhagáin library of Lower Ormond”, Peritia 24–25 (2013-2014): 213–229.  
The most prominent Irish legal family of their time, Meic Aodhagáin maintained a celebrated law school in Lower Ormond in northern Co Tipperary. Through the analysis of manuscripts produced by two fifteenth-century scribes who worked among Meic Aodhagáin, this study identifies some of the texts likely to have been kept at the family’s Lower Ormond school. From the resulting list it is evident that Meic Aodhagáin possessed a considerable collection of vernacular religious material, especially homilies and passions, quite apart from law books.
McLaughlin, Roisin, “A text on almsgiving in RIA MS 3 B 23 and the Leabhar Breac”, Ériu 62 (2012): 113–183.  
This paper presents a Latin-Irish text on almsgiving in RIA MS 23 P 16 (1230; the Leabhar Breac) and a previously unpublished Middle-Irish version which is found in RIA MS 3 B 23 (1227). Editions and translations of both texts are provided and the language of the latter text is discussed. Many of the Latin sources in the text are identified, and some general observations are made concerning the compilation and transmission of Latin-Irish texts. In addition, a transcription of the text as found in Oxford, Bodleian Library MS Laud 610 is given as an appendix.
