Admittedly, LLL is an obscure Shakespearean play. [Kenneth Branagh and Patrick Doyle have revived it, through adaptation into a musical film.]
LLL is highly original, with no known sources. It is very funny. It is full of linguistic jokes. LLL also has textual tangles, which require elucidation, by any editor. Because of the passage of time, many of the jokes [puns] require explanation, too. Mr Woudhuysen tackles these topics thoroughly and convincingly. He makes sensible choices regarding emendations of the text. He covers the stage history. He gives credit to previous editors. He deals with the positive reactions by eminent writers such as Thomas Mann and W H Auden. Despite its obscurity, this is a play to possess, and this is the edition to have.
