4 Enoch

A huge and fascinating ‘online encyclopedia of second temple Judaism and Christian origins’ maintained by Gabriele Boccaccini. It takes a while to get to know your way around, but this site is a tremendous resource for hard-to-find stuff, and is particularly strong in the history-of-the-history; i.e., if you want to know how a given group of texts like the Old Testament Apocrypha came to be bundled together under that name, or the printed publication history of the first Book of Enoch, or the history of scholarship of this or that aspect of early Christian thought, this is the place.
