If I had to pick one book on web usability, this would be it. I always keep it by my side as a reference when designing or updating websites. It’s amazingly informative, accessible, concise, humorous, and well designed.

While the underlying message of this book is "Keep it Simple", there are tons of tips most web designers either wouldn't notice or don't consider to be important. This one definitely deserves a spot on your desk if you expect to make money online.

The US government's usability web site. An amazingly deep resource. While the Fed gets a bad rap for poor service and bureaucracy, this site does its part to make the online experience as intuitive as possible.

This a great book for anyone starting a blog. They lay out how to get set up, and explain all the options. They detail the task of posting, getting traffic, and monitoring it. This book is thorough in spite of the fact of being less than 200 pages in length.

I find this book to be the perfect level for new affiliates of people who haven't experienced much luck so far.  It is a clearly organized book that will help you make sense of the ins-and-outs of Google advertising.
