Bibliovores is a tiny, 24-hour self-service secondhand bookshop tucked in Xujiahui’s Shanghai Industrial Building. There’s no staff, no cashier, and access requires solving a simple password puzzle, giving the space a slightly secretive feel. Shelves are packed with mostly English and French books donated by expats—everything from travel guides and cookbooks to thrillers and historical novels—with a loose, personal curation rather than a carefully selected collection. The shop runs on trust: you stamp your own books, pay honestly, and lock up when you leave. Quiet and intimate, it caters to night owls, book collectors, and anyone who enjoys browsing in a calm, unconventional setting.
