Since I am living in a tiny room in NYC I don't have a lot of room for big photography books. But I brought along one of my favorites that I own- _Bernd and Hilla Becher Basic Forms_ text by Thierry De Duve. It's a small book, but I look at it quite often for inspiration.
Also, I am impressed with the new _The Polaroid Book_. Really nice collection.
