Connexions is a depot of open source textbooks and lessons. Connexions has thousands of open source textbooks that teachers and students can access for free. I have written about the benefits of open source software and programs in the past which you can read by clicking here.

In the video below Richard Baraniuk gives a fantastic explanation of the benefits of open source textbooks. The video is almost twenty minutes long, so for those of you who don’t have the time to watch it all, I’ll summarize some of the main points of Mr. Baraniuk’s talk.
1. Open Source textbooks save public schools money.
2. Open Source textbooks are easier and faster to edit and publish therefore making textbooks more relevant to today’s changing world.
3. Open Source textbooks are often collaboratively written projects leading to the representation of multiple points of view on a topic.
4. Open Source textbooks are peer reviewed by more eyes than a traditionally published textbook.
