Roger McGough visits Cambridge University Library to see the wealth of poetry manuscripts held there. The works range from what is arguably one of the earliest poems in English - the Hymn of Caedmon, dating to a codex prepared by Northumbrian monks in the year 737. The programme ranges in time, then, from the Anglo Saxon period to contemporary work by Carol Ann Duffy and Ann Stevenson. Roger is joined by librarian John Wells, and the actors Juliet Stevenson and David Bamber. Producer: Mark Smalley.
