The Christmas Book Flood, known as "Jólabókaflóð" in Iceland, is celebrated every December 24th and involves the exchange of books among family and friends. This tradition fosters a love for literature and encourages shared reading experiences, creating bonds and strengthening relationships. It originated in Iceland during World War II when books became a meaningful gift option due to the scarcity of other items. The Icelandic Publishers Association initiated this custom by releasing new books in the weeks leading up to Christmas, and the first catalog of new publications, "Bókatíðindi," was sent to every home in Iceland. Celebrations often include cozy book swaps, reading marathons, and creating inviting reading nooks, allowing participants to enjoy the warmth of stories together. The day emphasizes the thoughtfulness of selecting books that resonate with recipients, making it a cherished part of the holiday season.
