Forms that Work: Designing Web Forms for Usability (Interactive Technologies)
"The humble form: it may seem boring, but most of your website's value passes through forms. Follow Jarrett & Gaffney's guidelines, and you'll probably double your online profits.” - Jakob Nielsen, Principal, Nielsen Norman Group"This book isn't just about colons and choosing the right widgets. It's about the whole process of making good forms, which has a lot more to do with making sure you're asking the right questions in a way that your users can answer than it does with whether you use a drop-down list or radio buttons.”  - Steve Krug, Foreword author and author of the best sellingDon't Make me Think"If your web site includes forms, you need this book.  It's that simple.  In an easy-to-read format with lots of examples, Caroline and Gerry present their three-layer model -- relationship, conversation, appearance.  You need all three for a successful form -- a form that looks good, flows well, asks the right questions in the right way, and, most important of all, gets people to fill it out.” - Janice (Ginny) Redish, author of Letting Go of the Words -- Writing Web Content that Works
