Jeremy's finished The Little Book Of Bookcamp and you can get one from blurb. (Above is just a screengrab, you can't click on that and buy anything, but wouldn't it be handy if you could?)
It's not just a good record of the day, it seems like the sort of thing that any worthwhile gathering should/will be making from now on. Far more useful than brochure and blurb for a future conference. Just show people the book of the last one.
