You have a legitimate beef, but shouldn't you be complaining to congress? (I just now clicked your link -- nice site! -- and I see that you live in Scotland. Not sure who you should complain to.) Instead of dealing with copyright in a serious and thoughtful way, in the US we get asinine and cynical legislation like the Sonny Bono copyright extension act and the DMCA. It's no wonder that average folks have no respect for copyright, and one certainly can't expect Google to show more respect than is required by the law.
I feel at least some of your pain -- I've written a textbook and pdfs of my book are widely available. I'm not sure what the new world will look like (and not sure that my current work on a new edition will ever be repaid). But I also recognize --- speaking here about my case, not yours --- that a large percentage of the effort devoted to a new textbook edition is all about marketing and killing the used book market, which for most books is a social waste. These incentives *should* go away. The current model is broken. (My editor argued with me about this until she read Chris Anderson's "Free".) I don't know enough about photography to have an opinion in your case. But we need a less corrupt legal framework for sure.
Anyway, best of luck with your work.
