Thus the new articles are the Introduction plus the ones by Reid, Rateliff, Schroeder, Agan, Larsen, Linton, and (presumably) McCormack; the reprints are the ones by Rawls, Enright, Crowe, Lakowski, Smith, Donovan, and Thum. So I'm in good company.
I shd mention that the front cover art is quite eye-catching: a striking piece of Yavanna Kementari by Ulla Thynell, an artist I don't know whose work I'll need to learn more about.
Here's hoping this collection sparks some interesting discussion.
