Trench Texts Find an On-line Home and Are Now Open-Source!

What follows is a (lightly edited by me) announcement from Bill Trench about some free (and now) open-source texts.  What's really exciting here is that not only has Bill found a place to distribute his texts on-line (through his own institution's repository), but that he has made the $\LaTeX$ source available under a Creative Commons license!  Thank you Bill for this tremendous gift to the open-source textbook community.

I thank Professor Jane Costanza, Head of Discovery Services, Trinity University, for including my work on DigitalCommons@Trinity. I also thank my Trinity University colleagues-at-a-distance Ryan Daileda and Peter Oloffson for their encouragement and consistent support. In particular, Professor Daileda created my personal webpage in March 2009 and has generously donated his time to maintain it since then. My contribution to the cause of free and open textbooks would have been impossible without his help.

Please forward this message to colleagues, friends, and students who may be interested.
