Couple of issues with that: 
-Very few developed nations read in Spanish. Donation books in other languages are usually just trashed.
-Getting this huge amounts of books would be indeed crazy.
-So books will stay at owners homes. Because there are books in developing countries. We´re not necessarily looking into getting more. We just want to have them shared so they can all be read 10-20 times, instead of just 1 or 0 times.<p>Yes, I´ve been evaluating the non-profit way, especially because it could be easier to get donations, but I want it o be sustainable. Seems like everything that gets donation money becomes inefficient.
