Ditto to Jake's comments as that is how I pretty much view BookShare books. I would never not download a book just because of its quality rating. Several reasons: my interest in a book has nothing to do with the quality rating. Quality ratings are subjective, not objective. I rather judge for myself whether a book is readable or not usable for my purposes rather than accepting an arbitrary judgment. After all, how long does it take to download and what is the cost? I have everything to gain, and nothing to lose, by checking out the book for myself.
