There's been lots of muddle over the Google book-scanning project, from confusion over what Google's actually doing to misinformation about the law governing it. Google's asking its users to help clear the air, asking for help correcting the half-truths like the old canard that fair use is a set number of words or percentage of the work.

In a message to the "Support Book Discovery" group, Googlers invite searchers to add sources to the debate:

If you want to help set the record straight, consider this your invitation to get involved. Below are links to resources where you can find accurate information about Google Book Search, copyright and fair use. If you see a misleading article or blog post, we encourage you to write a letter to the editor, post a comment or blog about the facts.

Hmm, I wonder if there's a search engine that offers pointers to reference books that might help in the quest...
