 Two works can be confidently ascribed to Sherwood, an Introduction to Logic and a treatise on syncategorematic terms, the Syncategoremata. The Introduction survives in complete form in only one manuscript, Bibliothèque Nationale MS. Lat. 16,617, from the late 13th or 14th century, which begins with the heading Introductiones Magistri Guilli. de Shyreswode in logicam, “Introduction to Logic of Master William of Sherwood”. The Syncategoremata immediately follows, and is likewise explicitly attributed to Sherwood. The Syncategoremata also survives in a second manuscript, Bodleian MS Digby 55, where it is again explicitly labeled, Sincategoreumata Magistri Willielmi de Sirewode “[Treatise on] Syncategorematics of Master William of Sherwood”, and Chapter Five of the Introduction survives in a second manuscript, MS Worcester Cath. Q. 13, written around 1293/94, and edited by Pinborg &amp; Ebbesen (1984).
