Dual Language Books

I ran across this site:

http://www.book2.de/

A HUGE collection of about any language you can think of with FREE audio and some FREE texts. Some files are complete but a lot say "demo version" so I don't know if a lot of the site is still in progress but you can also buy the texts at amazon.com if you want a book format for around $10).

It seems to cover all the basics like family, restaurants, some grammar etc. From what I've seen so far it is an interesting start in some languages that are more difficult to find resources on like Icelandic, Lithuanian, Estonia, Latvian, Bosnian and Ukrainian to name a few.
