The British Library possesses one of the most important collections of Syriac manuscripts in the world, with large numbers dating back to the second half of the first millennium CE. The publication of important Syriac texts from these manuscripts has been going on for some 180 years and still continues. The aim of the present volume is to provide a guide to these scattered publications: following the sequence of the shelf-marks (call numbers), for each manuscript indication is given of what texts have been published from it. For convenience, a concordance between Wright’s Catalogue numbers and shelf-marks is provided, along with a list of palimpsests and of joins with manuscripts in other libraries, in particular with those still in the Library of Dayr al-Surian in Egypt, the monastery which was the source of over 500 manuscripts and fragments purchased by the British Museum in the mid nineteenth century.
