“The Faire Withering, published in 1444, is a remarkable book that features a detailed account on how English magic declined after John Uskglass left England. Although the text contains many precise accounts of spells, many reviewers consider this text to be an angry book, but not so as Watershippe’s two other books:
A Defense of my Deeds while Wrongfully Imprisoned by my Enemies in Newark, 1459-60
Crimes of the Faire King, 1461?"
Jonathan Strange & Mr Norrell, Susanna Clarke

I cannot say I know what to make of the "The History and Practice of English Magic" page other than it is some sort of game based off Susanna Clarke's novel; an interesting find, at any rate...seems to be a complete list of all the texts mentioned within the Jonathan Strange & Mr Norrell novel.
