The Concise Oxford Dictionary of Literary Terms
Chris Baldick
You won't find everything in here. But the omissions are so few that you probably won't notice. Anacoluthon? Here. Aposiopesis? Here. Practically every unusual and obscure literary term you could need info on, as well as capsule summaries of the common terms you might need to check on...Magic Realism, post-structuralism, Surrealism, and so on. This is an ideal reference and at the least a good starting point for deeper investigations. (My comments are on the 1990 edition.)
