Law Librarian Blog today features an interesting post about items missing from the U.S. National Archives, likely through employee theft.
See Missing Items from US Archive, Found Item in UK Archive.
See also the National Archives webpage Missing Historical Documents and Items.
And see the U.K. National Archives news item Lost Page of American History Found at The National Archives about a rare print of America’s Declaration of Independence (dated 4 July 1776), named after printer John Dunlap (1747-1812) — one of only 26 known copies in the world — recently found among files at the British Archives at Kew.
Nice to have some redundancy, even if all the way across the Pond!
