And the works and books of  two brilliant minds of the founding era Thomas Jefferson and another thinker Lysander Spooner [both can be found online, just Google]
Hillsdale College and the Ludwig Von Mises Institute are excellent resources for libertarian and Constitutional purist free thinkers and anyone concerned with liberty.
American Deception is a site where 448 historical documents can be read & downloaded. The link is listed on this site, I might add that searching the Congressional Record is a mind boggling eye opener.

This list is in no way the end all reading list for those who seek the truth. It is in fact only a bit of what I believe should be required reading by any American who still values the ideals upon which our country was founded. There are volumes of references in these books. Why I put the Charlotte Iserbyt's manuscript at the top of the list, because it is most important to understand how those who feel compelled to "design" the social order [mainly to  their own benefit] have corrupted the institutions of learning to become behavioral modification laboratories. The studies of the real Abraham Lincoln is necessary in order to understand the true motives for the War that forced the corporate state upon America and destroyed the Constitutional Republic.
It has taken me years of digging and countless hours of reading to come to grips with the truth. Fortunately for those of you who are just beginning your journey the internet will make it much easier to find. You won't have to scour dusty basements of used bookstores for obscure volumes and  un-circulated volumes. You will have to sort through conflicts of corrupted views with actual facts. A word to the seeker, do not let your indoctrinated beliefs be an obstacle to objective consideration of truths that offend. Because you will quickly discover that the truth offends all we have been led to believe.

A word of warning: The search for truth is not for the faint of heart. It is a long and frightening journey through webs of deceit and corruption that has affected every facet of our lives. You will be treading where only the bravest of individual thinkers dare. You will have to work through years of being taught lies and coerced into behavior that robs you of your freedom and liberty. But for those who dare here are some books that will be a good beginning to getting a REAL education. Only the truth can set you free.
