This guide for trustees reports on the dangerous decline of academic freedom and intellectual diversity on college campuses. The foreword, by Benno Schmidt, chairman of the CUNY Board of Trustees and former president of Yale, comes at a time when duly-invited graduation speakers are made unwelcome, campus speech codes threaten the free exchange of ideas, and academic freedom controversies are emerging on a number of campuses. The guide features key documents that shaped the modern concept of academic freedom, coupled with commentary from a wide and bipartisan roster of distinguished educators, attorneys, and policymakers including former Harvard University president Lawrence Summers, U.S. Circuit Judge Jose Cabranes, CUNY board chairman and former president of Yale, Benno Schmidt, and the co-founders of the Foundation for Individual Rights in Education Alan Charles Kors and Harvey Silverglate. The report accompanied a conference on the same subject held in New York City on April 25, 2013.
