I don't really know what Google Books is all about, but I registered all the same. I uploaded the same PDF that I used for Amazon's "Search Inside" and I think it'll now take a while to hit Google.
I also printed out an address which is in Ireland where I need to send a hard copy. I'll blog again once I've figured out a little bit more about how this works.
The initial fear was over compromising copyright, but I'm willing to give it a go to see what happens for Tortoise George at least.
