Many of these materials were developed for the Open Course Library Project of the Washington State Colleges as part of a Gates Foundation grant. The goal of this project was to create materials that would be FREE (on the web) to anyone who wanted to use or modify them (and not have to pay $200 for a calculus book). They have been used by several thousand students.

The textbook sections, in color, are available free in pdf format at the bottom of this page.
Printed versions, in B&W, are available for Calculus I (chapters 0-3), II (chapters 4-8), and III (chapters 9-11) for about $18 each at
Alternate printed versions reformatted in LaTex are available at and or free online at
