I’ve enjoyed shopping at the Book Trader for as long as I can remember. The Book Trader is a popular used book store located on Second Street in Philly’s Old City neighborhood. Originally located on South Street, the store has been in operation for over 30 years. It’s everything you would want in a used bookstore – narrow book-crammed aisles, overflowing shelves, and friendly and helpful staff. Book lovers like me can get lost in here for hours. A true Philadelphia institution. Open every day from 10 am to 10 pm (except Thanksgiving and Christmas).
