All done by Brigham Young University, and are here. At the moment I think there is a problem with some of the links, but this will be fixed.
Most of the books are liturgical etc, but there is a Syriac New Testament, another containing Paul’s letters, a collection of Isaac of Scete and Cyriacus of Antioch, a couple of works by Barhebraeus including the “Chronicle of the ages”, and a Garshuni version of the world history of Michael the Syrian. Some unclassified “collections of religious works” might bear investigation.
