My two contributor's copies arrived yesterday, and I'm just tickled pink. As my first major professional publication, I've been waiting for this quite a while -- I finished the article by August 2015, had it accepted by October 2015, and now (sixteen months later) it's finally hit the world.
This is also the first actual copy of Tolkien Studies I've ever owned. Since my library offers free printing, I've just printed out all the essays that I've needed. In fact, I didn't even realize that TS came out as a book (rather than as a journal) until about a year ago.
I haven't had time to do more than skim through things, but I'm pretty excited about a lot of the contributions. And I'm always delighted by the "Year's Work in Tolkien Studies" section, which was perhaps the single most useful thing for my dissertation that I found.
