I know my publisher (Penguin) has been in contact with them, but I haven't reached out to them specifically myself. Wado for the suggestion! The book did just appear in Society of American Baseball Research's Fall Bookshelf, which was nice to see.

Oh you're really good to go with SABR - that's a serious audience and I'm thrilled they're recommending the book. I spent a Summer at the library when I was in grad school, so please feel free to say hi if I can be of help. I really look forward to reading it.
