Anne Ford writes: “Kathryn Heaviside, librarian and gallery coordinator at Northport–East Northport (N.Y.) Public Library, doesn’t do anything by halves. So when she got obsessed with tracking down different library card designs, she ignored her supervisor’s suggestion to limit her search to her home county. A couple of years and many, many emailed requests later, Heaviside has collected hundreds of public library cards from every US state and several foreign locales, including the Czech Republic, Hong Kong, Ireland, New Zealand, Pakistan, Poland, Russia, Scotland, and South Africa.”
