||Nathaniel Popkin, Peter Woodall and Joseph E.B. Elliott recently published a tome that catalogs years of exploring this city's secrets, many of them buried in plain sight. They'll talk about the process of exploring and how they got so many gorgeous photos, and what their work means for the future of preservation in Philadelphia. (Accessibility note: The presentation is on the lower level and there is no elevator.)
