I have a pretty large photo book library, by my wife's standards :-). Every single one was bought because I was first aware of the photographer's work, then went to find a book with his photos. Though it didn't matter who printed the book, the first source I go to is always Amazon, so I would place the vendor higher on my list than the production source. And if you aren't aware of it, it is possible for individuals to place their work directly on Amazon.
