Some favorites on my shelves...

"The Americans" by Robert Frank
"Warwick Mountain Series" by Phil Perkis
"Prague Panoramic" by Joseph Sudeck
"Passage" by Irving Penn
"Odyssey" National Geographic
"Treadwell" by Andrea Modica
"Ralph Eugend Meatyard" published by ICP/Steidl
"Frederick Sommer" published by Yale Univeroty Press
"Gertrude Kasebier" by Barbara Michaels

I find that Photo-eye can be a great source for hard to find out of print books, but you can get better prices through Amazon. (Got a great price on that Frederick Sommer book!)

Hmmm... it's been awhile since I bought a new photo book
