In a piece headlined "10 of the Oldest Continuously Operated Stores from Around the World," Mental Floss showcased a bookstore in the U.S.:
"Founded in 1745, the Moravian Book Shop in Bethlehem, Pennsylvania is the oldest continuously operating bookstore in America (the Bertrand Bookstore in Portugal opened 13 years earlier, and is generally considered the oldest in the world). While the Moravian started out as a place to buy and print religious texts, it changed with the times, and now sells every book under the sun out of its (significantly expanded) 15,000 square foot shop. Bookstore employees say the shop sometimes feels haunted by its lengthy past--literally. Rumor has it, a friendly ghost haunts the shop, occasionally reminding employees to turn off appliances they've left running."
