This site is so handy:  http://www.sacred-texts.com

It's more than various religious texts from different parts of the world...it's got a killer section on celtic folk tales, a killer section on legends and sagas from different places in the world, and other useful stuff like that.  I use it a lot.  And it has a decent section on Buddhist and Shinto stuff as well, which is why I discovered it in the first place.

It covers stuff from all over the world.  It's basically an db of scanned in, out of copyright books...very easy to use.
