The real reason why I was posting about the bookstore was that I found this OSS listing in convenient dead tree version, for free. I picked it up along with my other purchases, planning to punch a hole in the corner so I could dangle it outside my cube with a little sign reading "Free Thought Leadership!" so as to interest the management in free/ open software.
This apparently counted as 'purchasing' an O'Reilly book, and I got a free t-shirt.
It's a burgandy shirt ( comment from my wife :"oh, good. another geeky burgandy shirt. I'll be sure to fold it next to the perlmonks shirt so they can talk with each other") and has the Java tiger on it...
