Bio/Articles on L. Ravenhill

Does anyone know of any Bio or good articles on the Life of Leonard Ravenhill?

I read a good post on here yesterday called " A Remembrance of Leonard Ravenhill" and though I've heard many sermons of his, it sparked my interests to want to know more and read more about the man and his life- Thanks to any who comment.

Thanks, I really look forward to reading it. Please let us know when you have done so. Thanks Greg
