Midlothian Book Exchange, a non-digital bookstore in Midtown, is celebrating its 40th anniversary with a team of mother-daughter duo Dorryce Rudd and Caroline Davidson, who took over when Martha Graydon, the original owners, decided to keep the store analog and not sell books online. The bookstore still offers over 175,000 titles and is known for its gently used books. The store is celebrating the anniversary with reading challenges, book club meetings, and free totes.
