UPDATE on my "Philo or the Pseudepigrapha?" post: Thanks to Eric Sowell (also here), Torrey Seland, Stephen Carlson, Mark Goodacre, Justin Dombrowski, and Ed Cook for their comments on (and praise of) the post. I'm glad it was useful.

I should also have thought to mention my Old Testament Pseudepigrapha website, which has material from a course I have taught a number of times at the University of St. Andrews.

As for Eric's and Ed's question, yes, the Mishnah and the other Tannaitic rabbinic texts are relevant too, but I'm not an expert on them and am hesitant to comment about how to use them for NT background. Ed has some observations. I suppose also that NT scholars could get away with judicious use of rabbinic passages that Neusner has isolated on stratigraphic grounds to be from the first century. I have a bunch of notes on how NT scholars should (and shouldn't) use Jewish sources, from a postgraduate seminar I gave a few years ago. Maybe one of these days I'll pull them together into an article.
