AMSCO has Partnered with OpenStax
For any AP Gov teachers using, or considering using, the AMSCO AP Government and Politics book from Perfection Learning, consider pairing it with the free, online OpenStax text. These two sources complement each other nicely, make for an affordable selection, and tend to satisfy the College Board’s audit, as the OpenStax edition—written by professors at Rice University—appears on the College Board’s Example textbook list. Below are useful links and the visible PDF docs to explain or assist.
