In further celebration of our most recent myth-busting course, U.S. Constitutional History, we’re sending a free copy of Kevin Gutzman’s New York Times bestseller The Politically Incorrect Guide to the Constitution to all new members who request it! This offer is good through May 31, 2013.

At LibertyClassroom.com, you can learn the U.S. history, economics, European history, and philosophy your teachers didn’t tell you about, and from faculty members you can trust. And you don’t have to tune in at any particular time — download the courses and listen in your car, or watch on your mobile device. (All courses are available in video or audio.)

Plus, ask us all the questions you want in our Q&A forums for a year.

Scan our course offerings, check out our faculty, and join us! And don’t forget: claim your free book once you’ve joined!

NOTE: This book giveaway may not be combined with any other offer.
