Elementary Abstract Algebra: Examples and Applications

Elementary Abstract Algebra: Examples and Applications is a new open-source abstract algebra text by a number of contributors: Justin Hill, Chris Thron (eds), Thomas Judson, Dave Witte Morris, Joy Morris, A. J. Hildebrand, Holly Webb, Johnny Watts and David Weathers. 

According to editor Chris Thron:

"The treatment is far more elementary than any other book on abstract algebra that we've seen. The text is designed for students who are planning to become secondary-school teachers. We particularly emphasize material that has relevance to high-school math, as well as practical applications."

The link above will lead to both on-line (html) and pdf versions of the text.  Print-on-demand copies are available through Lulu.  There is also a series of supporting YouTube videos.

If you have used the text in its current form, please consider writing a review for the MAA Reviews website.  The previous blog posting describes best practices for doing so.

As a follow up to this blog posting, I hope to get some insight into how this large number of collaborators managed to work together.
