I finally did it. I subscribed to Zooba.
Wilhelm told me about this a while ago, having read about it on a blog he reads regularly, Lone Prairie. (Check out the 10 Lists of 10.)
Zooba is an online book club that sends you a book of your choice every month. Cost $10. No shipping. You can also order a book at any time for the same $10 with no shipping cost.
You create a list of books and they send you the book on top of the list. You can move the books around, delete them, add more, and otherwise manage your queue, much as you do with DVDs on Netflix.
My first book? Rough Crossings: Britain, the Slaves and the American Revolution (©2006) by Simon Schama.
