William Wade Hinshaw created his great work of abstracts of Quaker records by compiling entries on index cards so they could subsequently be grouped by surname. After publishing his six volume work, he was working with additional records with the intent to publish additional volumes, perhaps, when he died and the work ended. Those index cards that were never published reside in a card catalog file at the Friends Library at Swarthmore College. Some time ago I made copies of several of those cards, but today I am at a bit of a loss as to how to cite them. I keep asking, "What kind of source do I have?"
