Stan,

I used to own Miller's Photographic History and found it valuable for visual reference, but also a great set of books to just "thumb through" and be transported to another time. For those who don't own the books, Miller's Photographic history, all ten volumes, is online at Google Books.

Just go to this link and type in "Miller's Photographic History"
