Catalog of Snowden Revelations
This looks to be very good.
Add that to these three indexes of NSA source material, and these two summaries.
This excellent parody website has a good collection of all the leaks, too.
EDITED TO ADD (2/5): Another catalog site.

@ Bruce,
The “lawfareblog” link insists on having “javascript” turned on for mobiles. As it does not apparently alow access any other way I’m going to treat the site software with deep suspicion.
