Why Don't Book Publishers Object To Web Indexing?

Danny Sullivan over at SearchEngineWatch makes an interesting point when it comes to publishers objecting to GooglePrint.

"...woe to the publisher or member of a publishing group that is ever found during legal disclosure to have complained about not being indexed better on Google. You can't enjoy years of free traffic from a source, then suddenly decide that copyright law is now different just because the words appear in print, rather than on the web."
