Old Information

In June 2016, PCC was awarded a grant from the Oregon HECC to convert two popular open textbooks for calculus, APEX Calculus and Active Calculus, to the MathBook XML format. PCC is providing significant matching funds. We expect to complete this conversion (with enhancements) by the end of spring 2017. In December 2016 and May 2017 we will conduct formal peer reviews from Oregon colleges and Universities.


The repository of source files for this conversion is maintained on GitHub.
