Arnold's in the middle of a move and has to thin out his book collection as a result. As he tries to figure out what to keep he's been bringing in books to talk about in a new segment called "Classics in the field". If you've enjoyed Dave Arnold talking at length about obscure decades-old highly in-depth technical books, well he's doing that every week now.
I'm very happy that he's saved me the trouble of having to read "Pigeons: How to Make Them Pay"
