Unique Items in HathiTrust

In addition to their informational value, many items in HathiTrust have interest as historical, cultural, or archival objects.  This Civil War era diary of Lucius L. Shattuck stopped a bullet and the damage can be traced deep into the book.  The original can be found in the Bentley Historical Library at the University of Michigan.
