The most successful displays I've done at my library have been passive readers advisory. For the last five years or so, I’ve done a monthly display of minature books based on the top YA titles checked out in my library system, with the top 10 books getting four readalikes. The Tiny Library is a collection of tiny books based on our most popular titles. Each tiny book contains reading suggestions based on our readalike list. There is a QR code that leads to a Google Form where teens can choose the books they want to pick up from the library.
