Has anyone read "Journey Across Russia: The Soviet Union Today" by Bart McDowell and Dean Conger? It's a book of photos from all across Russia (I think it was sponsered by National Geographic). It was one of the books my dad gave to me that he used in college, and I must say it's probably my favorite non-Romanov photo book. It's got a wide variety of photos, including a few of imperial palaces. I don't know if it's still in print, but I highly recommend it to anyone interested in Russia itself.
