Some of our most cherished items are things we have preserved for centuries: Paintings, books, everyday objects that were used by our long-gone ancestors. On this episode, we’ll explore our desire to preserve things and what happens to our many collections. We’ll follow a plant and fish collection as it finds a new home and we’ll check in on the fate of old bones found on a construction site in historic Philadelphia. Plus, we’ll hear how Thomas Jefferson lost 30 years of research on native languages in one calamitous incident.
