Manuscript sharing: NYPL and Pennsylvania to share a Bill of Rights

The Wall Street Journal reports on an interesting 100-year sharing agreement between the New York Public Library and the Commonwealth of Pennsylvania for a manuscript Bill of Rights.The NYPL received the manuscript on donation in 1896 and its provenance before then appears to be uncertain. The WSJ article notes that only fourteen copies of the Bill were made (one for each state and for the federal government) and that Georgia, Maryland, New York and Pennsylvania are all missing their copies. Georgia's and New York's were probably lost to fire. (NYS's great and tragic 1911 Library fire destroyed a lot of early state history, including a lot of colonial era manuscripts.)
