Because I am finding so little time to work on this book and waiting until the book is complete to allow people to read it may mean the contents will be obsolete, I have decided to put the draft up on the web. The parts that are written are not as intelligible as they should be but they are relatively complete. There are some chapters or sections that are not yet at the stage that they can be disseminated and one that has not yet been started. I am currently (summer 2009) working on completely rewriting everything to try to make it easier to understand. I (and my publisher) am hoping to have the close to the final version done by September 2009.
You are welcome to download the old draft and use it for noncommercial purposes (note the copyright on the front of the draft). If you would like to be informed when updates are made and chapters are added, send me your email address (leveson "at" mit.edu) and I will send you a notice.
I welcome comments on how it can be improved but don't waste time on making comments on typos or detailed wording and content. I'm totally rewriting the book fron scratch to make things clearer and apply the things I've learned since starting this 6 years ago.
