Getting my copy of "THE FEDERALIST PAPERS" out again.
Yes, I understand. While youre at it, you might also try A Century of Lawmaking, http://memory.loc.gov/ammem/amlaw/lawhome.html, thats not a book, its a Library of Congress website with a huge amount of wonderful material for this subject.
Another excellent site, with what seems an endless library of original material is The Constitution Society, go to http://www.constitution.org/, and click on Liberty Library
