In commemoration of Providence’s 375th anniversary, the John Carter Brown Library presents "A Key into a 17th-century Mystery:  Investigating Roger Williams’ Shorthand," an exhibition around a mysterious 17th century book in the Library’s collection and its shorthand annotations. The book in question is a bibliographic enigma: lacking a title page and imprint information, scholars have been unable thus far to identify it. Subtitled, “An Essay Concerning the Reconciling of Differences among Christians,” it has been in the collection since the beginnings of the Library, accompanied by a letter asserting that the shorthand on nearly every page is Roger Williams’. Williams was a known expert in shorthand, having learned “the art of stenographie” as a young legal clerk. This exhibition will be on display in the MacMillan Reading Room, which is open to the public Monday through Friday 8:30 a.m. to 5 p.m. and Saturday 9 a.m. to noon. For more information, call 401-863-2725.  http://www.brown.edu/Facilities/John_Carter_Brown_Library/
