The Syriac Studies Reference Library is a joint project of Brigham Young University and the Catholic University of America, through which a number of foundational scholarly works from the 18th to early 20th century have been scanned from CUA’s own collection and made available online; most are unavailable in Google Books or the Internet Archive. One can browse by ancient authors, such as Nestorius, and topics, such as hagiography and historiography; or search by keyword. Textual editions and translations, studies, and research tools are all well represented. (Personal) highlights include Mitchell, Bevan, and Crawford, eds., S. Ephraim’s Prose Refutations of Mani, Marcion, and Bardaisan (London, 1912-21); Axel Moberg, ed., The Book of the Himyarites (Lund, 1924); and, with the interesting allusion to Caesar’s De Bello Gallico in its title, S. Assemani, Biblioteca apostolica vaticana. Bibliothecae Apostolicae Vaticanae codicum manuscriptorum catalogus in tres partes distributus: in quarum prima Orientales, in altera Graeci in tertia Latini Italici aliorumque idiomatum codices, vol. 2-3 (Reprint; Paris: Maisonneuve, 1926).
