I am teaching an AP US History class and we are discussing the tariff controversies of the 1820s. I wanted to discuss the Harrisburg Convention of 1827 and looked for some quick references. Nothing in the Britannica hard copy, nothing on Wikipedia. I then searched the Mises.org website and found a 22-page article on PDF by W. Kesler Jackson from The Libertarian Papers (2010). Many thanks to the Ludwig von Mises Institute for making this type of free market publication available.
