This week, Jer speaks with geographer/mathematician/curator/topologist John Hessler about what it might mean to map the Library’s holdings. We’ll also learn about how a left-handed draftsmanship contest changed veterans lives after the civil war, and we’ll take a peek into the journals of Greenwich Village impresario Izzy Young. Jer will also share some code experiments he’s been working on to map the Library’s lists of names to find polymaths - people whose careers span across many subject areas or conceptual domains.
