IBBY, International Board on Book for Young people, is an international non-profit organisation which aims to bridge the gap between books and younger generations.

In 2021, Legance signed a Memorandum of Understanding with IBBY, whereby it committed to support in particular the project “BILL – Library of Legality”. The project aims at spreading the culture of legality and justice among younger generations, by distributing volumes of a selected bibliography in suitcases and making them available to schools and libraries.
