Calculus Made Easy

The 1914 British second edition of Calculus Made Easy by Sylvanus P. Thompson is by far the most popular ebook I helped produce for PG. It was run at DP, and therefore represents a collaboration of many volunteers, most of them anonymous, but including Project Manager Chris Curnow and post-processor Paula Appling. A short description of the PG ebook was published in the DP Blog shortly after the ebook was first released in 2010.
