gutzmankThe Avalon Project at Yale’s Web site has a host of primary documents, including a few that I’ve linked to on LibertyClassroom.com.
Besides that, Freehling edited a good collection on the Jacksonian era, Greene edited a good set on the Revolutionary era, Banning has a good book of primary documents from the Early Republic, I’ve repeatedly assigned my students Linden’s VOICES FROM THE GATHERING STORM on the Antebellum period, and there are ongoing or complete multi-volume editions of the papers of Washington, Jefferson, Madison, Monroe, Hamilton, Marshall, Jay, Lincoln, Douglas, Franklin, the First Congress, the Continental Congress, the Philadelphia Convention, the Ratification of the Constitution, etc. Law schools’ chief textbooks are collections of judicial opinions called “casebooks.” The world is your oyster!
