The 1688 petition was the first American document of its kind that made a plea for equal human rights for everyone. It compelled a higher standard of reasoning about fairness and equality that continued to grow in Pennsylvania and the other colonies with the Declaration of Independence and the abolitionist and suffrage movements, eventually giving rise to Lincoln's reference to human rights in the Gettysburg Address. The 1688 petition was set aside and forgotten until 1844 when it was re-discovered and became a focus of the burgeoning abolitionist movement in the United States. After a century of public exposure, it was misplaced and once more re-discovered in March 2005 in the vault at Arch Street Meetinghouse. At that time it was in deteriorating condition, with tears at the edges, paper tape covering voids and handwriting where the petition had originally been folded, and its oak gall ink slowly fading into gray. To preserve the document for future generations, it was treated at the Conservation Center for Art and Historic Artifacts (CCAHA) in downtown Philadelphia. CCAHA conservator Morgan Zinsmeister removed previous repairs and reduced centuries of old and discolored adhesives with various poultices and enzymatic solutions. Acidity and discoloration in the paper were reduced through aqueous treatment. Repairs were made with acrylic-toned Japanese papers that were carefully applied to bridge the voids. Finally, the petition was photographed at high resolution and then encapsulated along its edges(not laminated) between sheets of inert polyester film. The petition was shown at an exhibit of original rare American documents at the National Constitution Center on Independence Mall in the summer of 2007. It currently resides at Haverford College Quaker and Special Collections, the joint repository (with Friends Historical Library of Swarthmore College) for the records of Philadelphia Yearly Meeting. Today the 1688 petition is for many a powerful reminder about the basis for freedom and equality for all.
