Here is one (no longer active) from 2008 which I purchased I think in late 2010 or early 2011: Kneb Knebaih's "The Public Domain Secret."

This guy put together a monster list of public domain links presented with great graphic design. Most, if not all, of the artwork came from the public domain. I think it was 283 pages for $10. That one book was very informative and productive for me, opening up a vast world of millions of free documents I don't think I would have known about without it.
Around 2012 or so, he mentioned he would be producing a killer revision/update, and teased a few pages, but I think he experienced some health problems and it never happened, and he hasn't been seen around these parts since. Still, the first edition was a great product.
Here is what one reviewer said:

"This is clearly a Magnum Opus on the Public Domain concept.
I agree with other's comments on the way the book is designed make it a very pleasant read, fun in fact, not just the normal black text on a plain background.
I agree that you don't nod off reading through this.
A very worth while purchase.
One of my favorites.
Get one for yourself guys/gals while the price is nice.
Good job Kneb."
