Today I finished a second round of proofs for my book. There were just a few things that needed more correction on the first set of proofs that I could not do with the web-based proofing system that my publisher is using. So the production team made the changes very quickly and sent me a complete PDF of the book to verify the corrections that they made. Everything looks good so things are now completely in the hands of production.
The Apress folks have been very easy to work with. Quite a pleasure to say the least.
Now I just get to wait until the book is published. September 21 is the target date.
