The number of Deventer editions of the Doctrinale is considerable, mostly containing the glosses of Hegius and Zinthius, which overwhelm the text with commentary; a single distich often receiving two pages of notes, so full of typographical abbreviations and so closely packed together as to be almost illegible.

Among the grammars was the Doctrinale of Alexander da Villa Dei, written in 1199. This rhyming grammar was enormously popular, and continued to be so, well into the sixteenth century. In the thirteenth century Albertus Magnus made a digest of all the works of Aristotle, which proved to be easier for students than the originals, and which were sometimes used in place of them.

He is said by Junius to have printed, about the year 1442 that is, two years after Koster's death the Doctrinale of Alexander Gallus and the Tracts of Peter of Spain, with the very types which Koster made use of in Haarlem; but as no volume of this kind has ever been discovered, nor any trace of one, the entire story is generally regarded as apocryphal.

The Speculum naturale gives a description of the world in all its parts, animal and vegetable and mineral; the Speculum doctrinale taught how to practise the arts and sciences; the Speculum historiale embraced the world's history down to 1250; and the Speculum morale, which is perhaps not by Vincent, found room for the philosophies. But few libraries can have possessed this work in full.
