From renowned legal scholar Cass R. Sunstein, a concise, case-by-case guide to resolving free-speech dilemmas at colleges and universities.

Free speech is indispensable on college campuses: allowing varied views and frank exchanges of opinion is a core component of the educational enterprise and the pursuit of truth. But free speech does not mean a free-for-all. The First Amendment prohibits “abridging the freedom of speech,” yet laws against perjury or bribery, for example, are still constitutional. In the same way, valuing freedom of speech does not stop a university from regulating speech when doing so is necessary for its educational mission. So where is the dividing line? How can we distinguish reasonable restrictions from impermissible infringement?

In this pragmatic, no-nonsense explainer, Cass Sunstein takes us through a wide range of scenarios involving students, professors, and administrators. He discusses why it’s consistent with the First Amendment to punish students who shout down a speaker, but not those who chant offensive slogans; why a professor cannot be fired for writing a politically charged op-ed, yet a university might legitimately consider an applicant’s political views when deciding whether to hire her. He explains why private universities are not legally bound by the First Amendment yet should, in most cases, look to follow it. And he addresses the thorny question of whether a university should officially take sides on public issues or deliberately keep the institution outside the fray.

At a time when universities are assailed on free-speech grounds from both left and right, Campus Free Speech: A Pocket Guide is an indispensable resource for cutting through the noise and understanding the key issues animating the debates.

This handy guide won’t tell you what the Constitution ought to say, nor what it ought to mean. It will tell you what the Constitution says and what it has meant.

A Pocket Guide to the US Constitution presents a straightforward way to understand the American Constitutional system. Without wading through lengthy legal prose, heavy historical analysis, or polemical diatribes, you can easily find out what the emoluments clause means, learn about gerrymandering and separation of powers, or read a brief background on why slaves in colonial America were considered 3/5 of a person.

Small enough to put in your pocket, backpack, or briefcase, A Pocket Guide to the US Constitution can be used to comprehend current events, dig deeper into court cases, or sort out your own opinions on constitutional issues.

For most Americans in the 1960s, Vietnam was a faraway land of which they had little or no knowledge. Yet soon, hundreds of thousands of young American men and women would find themselves on the other side of the globe, fighting—and, in many cases, living—with the Vietnamese people. To lessen the culture shock, the Department of Defense prepared A Pocket Guide to Vietnam, 1962, a remarkably compact and surprisingly timeless crash course in Vietnamese culture for visitors to this foreign land.
