4 out of 5 stars (based on 1 review)
I am using this site for the past months. No need for an account or registration, no ads, and you can download tens of thousands of books in different formats and languages. It is only one language available on the site tho. So check it out and let me know what you think. I would give so far a 4 out of 5.
Since this website is exclusively in Spanish, we cannot check if it is or not trade-free. This directory is only for english-based goods/services solely because we are unable to provide any relevant review for any other languages. Anyone is free to create a trade-free directory in any language they prefer. 😉
