Paul's Letter Collection: Tracing the Origins 

On the Origin of Christian Scripture: The Evolution of the New Testament Canon in the Second Century 

If you're not familar with David Trobisch, he's a bit controversial. His specialty is manuscripts, and so associations with both the Museum of the Bible, and NA28. And if you're evangel, go no further.

My interest, was trying to find an in-depth discussion on Paul's letters (however defined). For a gentleman like Paul, who  was verbose, controlling, and a 20 year mission career across Syria, Roman Asia, and Greece, a few random letters seemed odd.  And only one definitely a hit, early on. Then, the manuscript trail, approx 150 years later, a package of what's left.

But Trobisch goes into the manuscript pattern, in detail, and then offers his ideas (quite un-Logos-y).

His second book, from last year, takes another turn, again looking at the odd NT manuscript pattern. I initially couldn't see his point, until I tried to refute it.  I'm forced to pull out the early church fathers, yet again.

On the negative, he has the Biblical scholar bad habit of stating theory in the form of implied fact. So, you have to go slow, to catch his specific wording.
