Favorite Small and Large Books on the Historian's Jesus

This weekend I finished Dale C. Allison, Jr.'s Constructing Jesus: Memory, Imagination, and History (Grand Rapids: Baker Academic, 2010). It's a big book (588 pages if you include all the back material; 462 if you ignore the bibliography and indexes) and thoroughly documented. Allison focuses upon doing the historian's task with a nod to social memory theory. Instead of attempting to isolate and authenticate the historicity of this or that part of the broader Jesus-Tradition he focuses instead on reoccuring themes that emerge from the overarching Jesus-Tradition. I found his approach to be satisfying and honest. I have no doubt that it is currently my favorite "big book" on the historical/historian's Jesus. How it is not be when this is the book's final paragraph:

While it may be an ‘emotional necessity to exalt the problem to which one wants to devote a lifetime,’ and while I am proudly a historian, I must confess that history is not what matters most. If my deathbed finds me alert and not overly racked with pain, I will then be preoccupied with how I have witnessed and embodied faith, hope, and charity. I will not be fretting over the historicity of this or that part of the Bible.
Constructing Jesus, 462.

So, then, what is my favorite small book on the subject? That's easy. It's Anthony Le Donne's Historical Jesus: What Can We Know and How Can We Know It? I wrote about it on my old blblioblog back in 2012.
