Leon and I have just launched our book (in beta), Tick My Boxes.

It's a checklist for web developers, with 80 checkpoints of the key things to do when building a website.
If you build websites, you will know many of these things already. Having them in a checklist format, together with an explanation, helps you quickly tick off the things you should be doing. If you are new to building websites, the book will help you learn lots of the best practice techniques.
We released the book in beta so that we get feedback from developers which we will incorporate in the final version, to be released later in 2008.
The book is available for £9 from Lulu.
