Query: A must have for literature

I am an English literature teacher. As I was getting ready to teach poetry for the first time, I realized I needed a concise resource booklet of literary terms. Though it is possible to find any term you are interested in on the Internet, it is not nearly as convenient as having a book in hand. Also, I have learned quite a few new terms simply flipping through it. I have used this book now for years as a teacher and found it to be invaluable.
