In the early eighties, rare book librarian John Rathe pulled down a dusty box, wrapped in twine, from a remote corner of the Rare Book room. Attached to the box was a label that said: “Do not open until war is over.” Which war? The Civil War? The War of 1812? What he discovered was a box filled with disguised anti-Nazi tracts hidden in packets of tea and shampoo and concealed in miniature books both popular and scholarly.
