Mark, if you want to keep archive.org from recording your sites, you need to create a robots.txt file at the root level of your server:
http://www.robotstxt.org/wc/exclusion.htmlIf that's no longer possible, I think you need to contact them directly. Generally, they'll pull anything if you can prove you control the domain.
Realistically, if Google Print is going to be opt-out rather than opt-in, Google should at least make the effort to check established COCOA-style databases. This is a reasonable compromise, and one that would (a) respect the wishes of any author who's willing to make a token effort, and (b) save the Authors Guild from fighting Google in court over the legality of indexing.
