These library card socks are for everyone who remembers what libraries were like before computers! These cute book socks show off borrowing cards, the “other” library cards. Before the digital era, every book in the library came with a little card that would be removed and stamped by the librarian when the book was checked out. Wear these old-school library card socks and let everyone know just how long you have been a card-carrying reader.
