As an avid book collector, I also wanted to mention a great new website that I just discovered, First Edition Points. Before I buy any vintage or out of print book, I do extensive research online and this website has made that research so much easier! Even if I can't afford to buy a first edition, I like to know what one looks like. You never know when you might run across one in a flea market or thrift shop. I also like to know so I don't get fooled into buying a misrepresented or Book Club edition on eBay!
So the next time you are about to buy an old book, you might want to check out a first edition. It won't turn you into a model but it might turn you into a bibliophile extraordinaire!
