The Ancient World Online drew attention to recent open access publications from the Center for Hellenic Studies. These include Albert Lord's classic The Singer of Tales and Averil Cameron's Dialoguing in Late Antiquity. I haven't figured out how to actually access them yet, but hopefully will soon.
See also Brice Jones' blog post and Paul Barford's blog post about Josh McDowell's involvement in plundering mummies for papyri. From the sound of it, it looks like they may have dropped entirely the “first century copy of Mark” hype in favor of later dates.
Finally, see as well Jones' blog post about a papyrus which includes a phrase used by Paul in 1 Thessalonians.
