International School Library Day has been celebrated in many countries every year on the fourth Monday of October since 1999 at the initiative of UNESCO. And every year it is dedicated to a specific topic.
It was first proclaimed by the president of the International Association of School Librarianship (IASL), Blanche Woolles. In 2005, the official status of the holiday was confirmed by the new president of this organization, Peter Jenko.
In 2008, this event reached a new level - in January, project coordinator Rick Mulholland announced that the International Day of School Libraries will be transformed into a month - also international. In October of the same year, the first International School Library Month was held under the motto "Literacy and learning - in your school library."
