Robin Hood and the Outlaw/ed Literary Canon [PDF ebook] 

This cutting-edge volume demonstrates both the literary quality and the socio-economic importance of works on ‘the matter of the greenwood’ over a long chronological period. These include drama texts, prose literature and novels (among them, children”s literature), and poetry. Whilst some of these are anonymous, others are by acknowledged canonical writers such as William Shakespeare, Ben Jonson, and John Keats. The editors and the contributors argue that it is vitally important to include Robin Hood texts in the canon of English literary works, because of the high quality of many of these texts, and because of their significance in the development of English literature.
