I love to read, and am always looking for new books. Even though I don't participate much, I love discussions about books!
This book is also designed with teaching in mind, but it has for more concrete examples/practice exercises to be used in a classroom setting. Published more recently, a lot of the topics are more up-to-date.
Unfortunately, not useful for my purposes, because it's largely composed of exercises for Spanish/French interpreters, and not much theory. Probably good for those audiences.
