Query: Excellent book, nice author

Not only is the book excellent in that it has lots of pertinent material for the sorts of work I am doing in Access, but when I did have a small problem with one of the examples, the author responded immediately to my request for clarification, and all has gone well since then. I didn't have any problem with downloading the code.I have many books on Access development, some good and some not so good. This one is always on the top of the stack for reference.
