Books to teach myself other languages?
 

I've recently become really interested in other countries for various reasons, and this has led me to wishing I knew more than just English. I'm assuming there are books that can help me to learn different languages? I'm actually interested in learning ANY other languages...but at the top of my list would probably be Spanish, German, and French. Obviously I'd like to do one at a time, where do you suggest starting? And what (if any?) books do you recommend? Thanks a lot for any help.

I like the Rick Steves series myself. The books are small, inexpensive, and they quickly teach you all the common words and phrases that people use everyday. You get up to speed pretty quickly. I have the German/Italian/Spanish/French books.
