We are having some problems with the electronic resource listed above. In the meantime, you can use this service by performing this workaround:
HISTORY RESOURCE CENTER - U.S.
Since we are having problems with viewing History Resource Center - U.S. in the Internet Explorer browser, you can still get to that resource by linking to History Resource Center - World.
Notice that there is a drop box under the search input box. You can choose "History Resource Center - U.S." in the drop box. Although the header at the top will say "World," your results will be limited to the U.S. if you choose that option.
