Probably the most important milestone was March of last year, when we assembled a complete version of the book and made it available for free on our web site and also for a reasonable price ($30) on lulu.com.
In the past year there have been two other milestones:
- We are now listed on the American Math Institute's Open Textbook Initiative site.
- We have several outside adoptions: classes at the University of the Puget Sound, Grinnell College, Casper College and Luzurne Community College are all using our book.
March seems to be a good time to update the book in anticipation of fall adoptions, so I've been working V2 of the full pdf. It's really just about ready, but I'm going to allow a bit more time pick up more errata from V1. Particular thanks to students at Luzurne CC, who have found several typos.
