Here is a website that is short, but pretty good, gives a some of Ven. Emmerich's visions of Jesus's scourging (it'll make you cry)and some links. There is also some information on her at the online Catholic Encyclopedia. This link has a link to TAN books that alot of her writings can be found at.

Last night I was reading about Padre Pio and some of the supernatural things that he did. Great reading.
What an awesome God we serve eh?
