Ernster, the Virtual Library Cat at Hofstra's Dean Law Library blog, reminds us of the Constitution Finder, a database maintained by the University of Richmond School of Law that "offers constitutions, charters, amendments, and other related documents. Nations of the world are linked to their constitutional text posted somewhere on the Internet." An easy to use pull-down menu provides links to, as Ernster reminds us, "English translations of over 200 countries' constitutions. . . . Each links to that nation's current constitution in both English and the native language, and in many cases to historical constitutions and other related documents from official government web sites."
So a tip of the Law Dawg's hat to Ernster the Virtual Library Cat for a great research suggestion.
