The Grace K. Babson Collection of Newtonia includes a library of over 1,000 volumes of English and foreign language editions of Newton's works (many of which are autographed and annotated in Newton's hand), manuscripts, engravings, artifacts, and other Newton memorabilia, including a death mask that originally belonged to Thomas Jefferson. The collection was acquired through the efforts of Grace Knight Babson, first wife of Roger Babson and is the largest source of Newton materials in the United States. The original 1950 printed catalog is available as a PDF.

A unique feature of the collection is the actual fore-parlour of the last London residence of Sir Isaac Newton. Novelist and diaristFrances Burney describes the room where her parents entertained many interesting guests during their period of owning the house.

Another unusual piece from the collection is our fourth-generation "Newton" apple tree, which grows on Babson campus.

The collection is currently on loan to Huntington Library in San Marino, CA.  From 1994 until November 2006 the collection was housed in The Burndy Library at The Dibner Institute for the History of Science in Cambridge, Massachusetts.  The closing of the Burndy Library in 2006 necessitated a move and the Grace K. Babson Collection of the Works of Sir Isaac Newton followed the Burndy Collections to the Huntington Library. There is a direct link to their catalog.

The Newton Project, hosted by Sussex University, is another excellent effort make available the scanned works of Sir Isaac Newton from sources all over the globe.
