To the seven titles traditionally recognized as Notker's shorter works ("De partibus logicae," "De syllogismis," "De definitione," "De arte rhetorica," "Computus," "De musica," and his letter to the Bishop Hugo of Sitten), the volume adds three texts, all new to the Notkerian canon - the St. Gall tractate ("Incipit quomodo septem circumstantiae rerum in legendo ordinandae sint"), "Distributio omnium specierum nominis inter cathegorias Aristotelis," and "De dialectica." The manuscripts of the texts have been closely followed in this diplomatic edition. Several codices have been identified and incorporated for the first time. A companion volume, "Notker latinus zu den kleineren Schriften," comprising Notker's largely Latin sources, will be published later.
