If you haven't read 'Qumran and Jerusalem: Studies in the Dead Sea Scrolls and the History of Judaism' it's quite interesting. It's part of the Dead Sea Scrolls collection or can be purchased alone: http://www.logos.com/product/17011/qumran-and-jerusalem-studies-in-the-dead-sea-scrolls-and-the-history-of-judaism
The title is a little misleading; it actually covers a lot of ground that some of the other 2nd Temple judaism ones don't.
Most interesting is just how many pseudepigrapha there were. You really wonder about the 'purchasing' audience. Real book worms. And great imaginations too.
But most interesting were what I didn't know about and thus the title: pseudepigrapha quoted inside the pseudepigrapha! And appararently these were NOT real works but mentioned to support the claims of the PG authors. Those guys were definitely 'pseude'.
This may be one reason that Logos has selected not to carry them (at least at this time).
