Oh, man, I completely ripped this off from Doc.
New, in the sidebar: some randomly selected titles from my library, courtesy of LibraryThing. It's dead simple to load your recent Amazon.com orders into this database, and it also reads Delicious Library databases (a wonderful Macintosh media cataloging program.)
Full disclosure: The titles have our Amazon Associates code embedded in them, so if you click on a book that looks interesting, and then buy it, you automatically make a small donation to the Enrevanche Latte Habit Maintenance Fund.
And we appreciate it.
I liked LibraryThing enough that I've paid for a year's membership. If you're a booklover, check it out.
