Michael, I wanted to learn more about Release It!, so I clicked on the link in your signature and was taken a page on the Pragmatic Programmer's site that featured a picture of the cover for Release It! -- however, the title on the page is "Enterprise Engineering". I thought that might be the book category, but there's another section just below the picture titled "Enterprise Engineering" and the About This Book section refers to it by the same title.
I suspect that there was a title change late in the process - either that, or the Release It! page has the wrong book's descriptions on it.
I hope this helps, Burk
