This collection contains twelve boxes of folders containing work in all stages of progress from scraps of annotated and virtually illegible paper often containing references to passages in a wide variety of authors, handwritten notes - again many very difficult to read, typed-up passages, photocopies of the same. Much of the material relates to the two Shakespearian plays, 'Love's Labour's Lost' and 'A Midsummer Night's Dream' (see detailed list), but there is also a small collection of literary papers by Clayton under the pseudonymns Frank Clare and Riki.
After the publication of his Jackson Knight memorial lecture, 'The Hole in the Wall: A New Look at Shakespeare's Latin base for 'A Midsummer Night's Dream', Professor Clayton had hoped to write a book expanding the same idea but also using it to explore some other plays of Shakespeare, particularly, it seems, 'The Winter's Tale' and 'As You Like It'. He also started to explore some related themes in Jonson's 'The Alchemist' and Lily's 'Midas', and Dickens' use of unusual names in 'Dombey and Son'.
There is also certain amount of further miscellaneous material in the collection, including personal material, lecture notes, copies of articles etc. (see handlist for further details).
