I got an email from Packt Publishing to review a book that they will be releasing very soon (March 2010?). The book is about OpenX.
In all honesty, I have not even tried to use OpenX Ad Server yet. Still, I am interested in this book because I also serve ads on this blog; too bad though that the ads on the sides are not enough to pay for the hosting 
I will have another update for this book once I have read it. I got a free ebook so I will have something to read on my 14-hour flight back home. 
Here is the book in detail:
- Learn the essentials of online advertising from the advertiser and publisher points of view
