I used this book in my undergraduate Classical Mythology class. It's one of the few textbooks that I didn't sell back; because I wanted to keep for further reference. Even more amazing, I actually have
used it for reference and perusal many times.
I recommend it actually exactly for that purpose. If you like Mythology at all, it's really handy to have in your collection because you just check the table of contents, find the myth and BOOM; short and sweet, easy to understand.
