In order to provide free books in the easiest and quickest way to our users, we use direct download links for our shared files. We check the download links twice before posting the books and test the links to avoid errors. But sometimes due to any number of factors, there may be books with missing or broken download links. If you found any book with a broken link, please let us know by either dropping a comment below, filling our contact form or sending us an email at firstname.lastname@example.org including the book title and author. We will fix it ASAP so you can download your desired book. Thank You.
