UNESCO has named Tbilisi, capital of Georgia, World Book Capital 2021. Throughout the year hundreds of events are held all over the city to celebrate authors, stories, and readers with an ultimate goal to help everyone find their next book to read. To make it easier to navigate through different reading choices, we turned the city map into a colorful map of books. Fully modular design system serves as a shared visual language for digital and physical applications - from branding giant book festivals to intimate writing workshops.
