My latest used library book purchase is a hardcover edition of It Can Happen Here: Authoritarian Peril in the Age of Bush by Joe Conason for 3 dollars. It's from the Anchorage library system.
I've already read this book before but wanted to have it in my collection, since before it's publication I had been wanting for some time (several years) someone to write a book with that concept (exploring the relevance of Sinclair Lewis's dystopia It Can't Happen Here to current conditions in America.) An excerpt and introduction of the book can be read, here.
