This site has been here for a while, and it has many, many links to all sorts of information including lots of Statistical and Political information, plus other Social Science sources.  There are so many links that your librarian did not test all of them. Some may no longer work, but many good ones are there.

Go to this site and choose a category, i.e. U. S. and World History, then a sub-category, i.e. U. S. History, then scroll down to find links to some useful information.
