From the Boxes and Arrows blog:
They did an interview with Steve Krug, who wrote a most eye-opening book on web usability, Don’t Make Me Think…
“But in the meantime I’ve had a change of heart, and decided to do an updated edition of Don’t Make Me Think first, then write the how-to testing book. The second edition of Think is due out later this year.”
So, two books:
1. Updated version of Don’t Make Me Think – should be a good one to pick up
2. He’s planning to write a how-to book on low-cost/no-cost usability testing.
When they come out, READ BOTH OF THEM.
