The July 2010 issue of Common-Place carries a brief notice by Arthur Rolston on The NBER/Maryland State Constitutions Project, which Rolston describes as "a much needed source providing in a single database the text of virtually every version of, and amendment to, every state constitution from 1776 through roughly 2000. The National Bureau of Economic Research, the National Science Foundation, and the University of Maryland support the project, with research undertaken under the direction of John Wallis, professor of economics at the University of Maryland."
