I got an advanced copy of my "Learning Perl Study Guide", and I'm happy to see it has an ISBN (1-60033-059-2, which is a publisher code I haven't seen O'Reilly use before). It's the same face size as Learning Perl, so it should be easy to bundled them. It's almost a real book!
It still needs a couple of changes, and I don't know when you'll be able to buy it, what price it will be, and so on. It's not available on Amazon yet, but I think the sales reps know about the book and it should be in the catalog very soon.
