This can work as a Christmas Wishlist or a New Year's Resolution. This year I've slowly but surely been adding to my book collection (and next year I wish to continue the collection further). Having a friend who works at a book store certainly helps. I've found a few online though, so here's a few ideas if you've been looking yourself.
Fair warning though, this list is probably something that would make those who are passionate about classics want to burn me at the stake. I love history and things I can keep around for inspiration. This is just a look at things that have sparked my curiosity, mainly when browsing through Amazon when I can't sleep.
