The Free Lecture Notes Page

This page contains links to various mathematical lecture notes or course notes which can be downloaded more or less freely. For all courses you can download a PDF file with the notes (which you should do if you just want to read them) or you can download the source (which you should do if you want to change the notes.)

Keisler's “Calculus: An Approach Using Infinitesimals.”

This is a radically different calculus textbook at the college freshman level based on Abraham Robinson's infinitesimals, which date from 1960. Click here for Keisler's web page.

Guichard's Three semester Calculus Book.

Used at Whitman college, includes source in e-plain TEX. Link to the author's web site.

Garrett's First Year Calculus.

Notes by Paul Garrett used for a “Calculus Refresher course” at the University of Minnesota. The author  offers both a postscript version of the notes and a complete TEX file of the notes. Check with author for copyright. Link to the author’s website
