If I can just re-emphasize the point which Paul raised; if you are an author of something on this Wonderful World Web, then taking various sections of your work and 'googling it' can produce many a surprise.....it's not exactly 'data-mining' but produces results....ie. links to sites hosting your material

I feel that any accurate (but pirated) information which indirectly leads to improved animal welfare, etc is great, but as you say, it's nice to be acknowledged and credited!
