(If this question has been answered before, or should be discussed elsewhere on this site, feel free to re-direct me.)

I just downloaded a document from here, "The Didache" by the Apostolic Fathers, which might fit in nicely with my current research paper on medieval education (thanks yet again, weatherwax!).
But, how would I go about citing an e-book obtained from this site in my bibliography? Does anyone know if there are rules in place about that? Should I just give the URL for the thread I got the download from, and the date I got it?

Help, or even just opinions, are appreciated, as I'm sure I'll run into this issue lots more times in the next few years...
