As a librarian myself I can tell you that our nation’s libraries hold many of our country’s greatest treasures.  This goes for the Library of Congress across the street from the Capitol Building to the tiny institution somewhere in Smalltown America with its Vertical File of irreplaceable local ephemera.  Through December 31st one our country’s best public libraries has a cross-section of its Civil War era artifacts on display.  My personal favorite (seen in the video) is the William Lloyd Garrison death mask.  I have seen the Lincoln death mask at the New-York Historical Society and there is something moving about seeing such an item knowing its provenance.
