To acclimate myself to Discover, as I started my research for the National History Day resource guides, I would look up random topics of interest and see what items HSP had within its holdings. My interest is in Abolition, so I began to type  familiar terms and to my surprise a name I least expected popped up, Thomas Clarkson.   I clicked to find a number of Clarkson’s works available at HSP. So I began to dig deeper, what was the connection? Why did a historical society in Philadelphia hold so much work of a British Abolitionist?  Through my research I found Clarkson was deeply inspired by Anthony Benezet’s “Historical Account of Guinea” (in the holdings of HSP).  In addition to his writing on the treatment of slaves and ending of slavery, Clarkson published books on Quakerism and a Biography of William Penn (also in the holdings of HSP). The Clarkson-Philadelphia connection runs so deep that when the Committee of Education of the Pennsylvania Abolition Society built its own school then named it Clarkson Hall. This exercise turned out  not only to acclimate me to the depths of the Historical Society of Pennsylvania's holdings, it was also a wonderful reminder of the interconnectedness of the Abolitionist Movement.
