Do you know if the Latin is online anywhere?Adam, I was doing research on Wyclif this Spring, and I found that Wyclif's writings are not easily procured. For one thing, many of his important works (such as Summa de Ente) were written in Latin, and remain yet untranslated. Of his English works, such as those printed in Select English Works of John Wyclif, some are regarded by Wyclif scholars as being spurious works made by Lollards after Wyclif's death. The whole set is in very antiquarian English.
At the present, there is quite a dearth of good, accessible Wyclif materials. I am unaware of any existing complete collection.
