Introduction

This is a listing of 82 sites that legally offer free textbooks and written course material.

There is a separate page with links to free audio and video courses  Free Audio & Video Courses Online

To the best of my knowledge all of the websites listed here offer only content that they are legally entitled to transfer to you. If you find a site listed here that you know illegally offers copyrighted material, please contact me through the site with a link to the infringing content. Mr6n8

To the best of my knowledge every website listed here, and its downloads, are safe. By the rules of this site, no website that has a red or an orange rating at Web of Trust (WOT) is allowed in the listings. I also use LinkExtend, a browser addon that offers the ratings from six other website rating products, to verify the sites here are clean. I have never encountered any issue while visiting these sites. Additionally, I have downloaded something from every site that offers a download and have never encountered an issue. If you should ever encounter malware on any of these sites, please contact me through the site and provide the link to the offending content. Mr6n8

This was some great research in finding these books and courses. Gismo's has always been a source for everyone and stays green at Web of Trust. Unlike some that front green then redirects you to a malware / virus site. Keep it up.
