This book wouldn’t exist without the open source and Creative Commons licensed work of Gregory Hartman and David Austin.
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.
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, Steven Clontz, and Oscar Levin, and for Franciscan University of Steubenville granting me a sabbatical.
