If you’re reading this, there’s a good chance you love books. You probably also appreciate librarians, the curators of those beloved books, that have been bringing us the latest and greatest and protecting our right to read since libraries were first established. Within those library walls, we can explore puzzle-packed adventures, riveting tales of magic and illuminating truth about our past through the pages of a book. But adventure also lies within the library itself. So many books are written about our trusted institutions and the librarians that work there—taking readers to a place where connections are forged and new worlds unwrapped.

To celebrate National Library Card Sign-Up Month, what better time to put the smartest card in your wallet to good use and check out a book or two about libraries?

Travel to a library where an icy cold murder and a patron collide or discover how a chance encounter with a list of library books helps create an unlikely friendship between two very different people in a London suburb. Mystery, historical fiction, biography, fantasy—it’s all here, and it all takes place at the library!

Bookworms, grab your library cards and borrow any of these ebooks or audiobooks about libraries for free on the Libby app.
