I tagged all three sites explored in the exercise. While I would not enjoy reading a book on my computer, students may think it is just great. And I would not want them to print a free eBook using my library printer, they may not mind doing that from home. I can see great advantages to having these titles freely available to anyone who wants them.
I especially enjoyed the audio eBooks. I listened to parts of Walking by Henry David Thoreau and parts of "Jude" from the Bible.
Finally, the free books site is an excellent resource. I will explore this further with the language arts department in my school. We are always looking for ways to get more books into the hands of the students.
