This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
I'd say that it is the current edition of the book. However, please do confirm the name and cover-page of the book which appears to be different from what I purchased here at Amazon. Anyways, I'd say you are probably looking at buying the right book
