UPDATE (22 January). Two things. First, the dead link has been fixed. Sorry about that. Second, Deane Galbraith e-mails:
I have just added an online pseudepigrapha site to Biblical Studies Online. The sidebar won't list a separate pseudepigrapha category, because we're avoiding (as far as one can) the canonical/non-canonical distinction. Instead, ancient Jewish and Christian literature (itself a problematic distinction, as you well know) is listed under each genre - whether canonical or non-canonical.
