On September 26, 2013, John Sides alerted Washington Post’s readers about a Web site -Constitute- that lets users explore every single constitution of the world or, at least, of almost all the independent states in the world.
You can find search by country and by topic. Interested in which constitutions have provisions for the right to bear arms? Or gender equality? Or free speech? You can look for it.
The Comparative Constitutions Project (CCP) is directed by Zachary Elkins (University of Texas, Department of Government), Tom Ginsburg (University of Chicago, Law School), and James Melton (University College London), in cooperation with the Cline Center for Democracy at the University of Illinois. The project is supported by the National Science Foundation (SES 0648288).
The intent of the project is to investigate the sources and consequences of constitutional choices. Towards this end, the investigators are collecting data on the formal characteristics of written constitutions, both current and historical, for most independent states since 1789.
