Strand's has such a good collection of art and photography books, it's amazing. There's a good mixture of both used and new books. And the prices are unbeatable. I've gotten a lot of biographies here on Monet, van Gogh, Raphael, Manet, etc. And I've saved a lot. I love their calendar sales as well. New calendars for more than half off sometimes. They have really huge calendars too (black and white photography of major cities).
