Parrington and more at UVa

The American Studies program at University of Virginia has a number of nice resources on their website, including all three volumes of Vernon L. Parrington's Main Currents in American Thought:

• Vol. I - The Colonial Mind [my students should bookmark this one now!]
• Vol. II - Romantic Revolution in America
• Vol. III - The Beginnings of Critical Realism

Parrington is rather old school but also very good. These volumes were one of the key influences on me at an earlier phase of my education.

While you're on the site, also check out Erastus Salisbury Field's magnificent The Historical Monument of the American Republic.
