I just got done a great book on building usable forms – Luke Wroblewski’s “Web Form Design – Filling in the Blanks”. It was a really well-done, interesting book on a less than interesting topic (well, to most people) – in fact, it’s one of the best usability books I’ve read in terms of giving quick, easy-to-read, usable information. From my review on Goodreads.com:
“Good or bad, there aren’t many books that I can use for my job that I go through quickly. There’s just something about a limit to my absorption of information from these books that makes me take my time to get through them. However, that was not a problem with this book. Chock full of good information, Wroblewski manages to make it a quick, easy and yet informative read that only took me 2 days cover-to-cover.”
You can see more on Luke’s website, to get a feel for the book.
