I have learned much about what to include and how to teach the material for our audience from my colleagues David Burton, John Coleman, Justin Greenly, and Rachel Perrier. In addition, Valerie Plaus suggested the subtitle, and was brave enough to use this text with students, even before it was really finished.
I am indebted to Rob Beezer and David Farmer for PreTeXt, Alex Jordan for WeBWorK integration and help, and Brad Miller for Runestone. The platform affects what you write, and while I was writing I had in my mind the student and instructor experience of the html book being hosted on Runestone.
Finally, I am grateful for the encouragement, ideas, and technical help provided by David Austin, Matt Boelkins, Tien Chih, Steven Clontz, and Oscar Levin, and for Franciscan University of Steubenville granting me a sabbatical.
