All $20 goes to relief efforts for Haiti. As a free gift, I get a pile of PDFs. How can I not give this a perfect rating?
Sure, the overwhelming majority of PDFs I have zero use for, but there is easily two dozen things I do want, making this an exceptional deal. And those things I have zero use for? You might value them and find the stuff I want useless. There's something for almost everyone!
Thanks to OneBookShelf and the many, many publishers who put this together.
It's a shame there is no way to download groups of files at once. Not everything (there is stuff in here I'll never use, so no sense downloading it), but batches.
