I'll be guest blogging at the Powells.com blog every day next week. I've been saving up some good stuff for my stint over there, so it should be fun. And while you are there, be sure to look around at their amazing collection of used and new books. Just be glad you aren't in the store itself, otherwise you would do as I do--spend way to much money on books you can't fit into your suitcase.
On the other hand, if you buy enough books online, you get free shipping.
