Just finished reading the book Joel on Software: And on Diverse and Occasionally Related Matters That Will Prove of Interest to Software Developers, Designers, and Managers, and to Those Who, Whether by Good Fortune or Ill Luck, Work with Them in Some Capacity. This is the dead tree version of select articles from Joel Spolsky's Joel on Software (definitely easier to read than online, and I positively do like dogearing my books). Needless to say that I highly recommend it.
The next book is already in the mail: Paper Prototyping by Carolyn Snyder. Like I said, one down, n to go.
