While I am not a camera collector by any means (cameras and gear do not hold any sentimental value for me), I am, however, a big collector of photo books.
Some of my favorites from my collection are
As Pete mentioned, The Americans by Robert Frank
The Ballad of Sexual Dependency by Nan Goldin.
I have several large books by Sebastiao Salgado- all of them are superb.
The Fat Baby by Eugene Richards
Living With the Enemy by Donna Ferrato
Those are just a few that come to mind right away. I am always stopping at garage sales, flea markets, used book stores, etc.....looking for really good photo books.
There is nothing like making myself a nice drink, settling in a comfortable chair next to nice reading light, and opening up a good book of art.
