Yeah, I think it is published by Lulu. The book's in my dorm and I'm not, so I'll just have to go by memory. But he has a pretty cool website there that teases and has links. Sort of a cult work, I think, but there are plenty of us who like a good journal-based zombie book.
Munk, I don't think he's an established writer. He's just a guy on another forum that I sometimes attend, not dissimilar from yourself. Maybe you could email him? He seems like a very decent fella from his posts over on the zombie/survival forum.
Hope this helps you out. I'm still waiting anxiously for that Munk book to add to my collection!
