Sylvie Vassallo, who has led the Montreuil Children's Book and Press Fair for 25 years, is stepping down and will be succeeded by Nils C. Ahl, who is set to take up his position on September 29, less than two months before the 42nd edition of the fair. The transition will not involve a major event, and the recruitment process, initiated in January by the Center for Promotion of Children's Books in Seine–Saint-Denis (CPLJ-93), resulted in a unanimous choice after reviewing 52 applications. Sylvie Vassallo, who is claiming her retirement rights, will continue to support the transition for several months. The CPLJ-93, created in 1984, leads projects throughout the year at the departmental, national, and international levels and claims a network of 1000 field partners. The association is chaired by Sylviane Giampino, also president of the Council of Childhood and Adolescence and vice-president of the High Council of Family, Childhood and Age. Its School of Children's Books, created in 2011, provides training sessions and intervenes with professionals in early childhood and animation to train them in literary mediation. The City of Paris has recently inaugurated its first School of Out-of-School Activities, with mandatory training for future part-time staff and plans for reinforced tracks and six pedagogical days per year in schools. In Montreuil, they have worked for fifteen years on how to give adults around children the means to bring books into their daily lives. Sylvie Vassallo emphasizes the importance of considering children's literature as a vector of cultural democratization in a department marked by strong social inequalities, making this ambition a concern for the entire interprofessional sector. She highlights the long-standing difficult recognition of children's literature, relating it to the place given to childhood itself and to transmission jobs very feminized. Nils C. Ahl, a translator of Scandinavian languages, has long collaborated with Le Monde des Livres and was still publishing a review on September 7 dedicated to the novel by Sara Stridsberg. After a stint in the City of Paris, where he worked on housing and architecture issues, he took over the foreign department of Phébus editions in 2015. He later turned to humanitarian work, with missions in Africa, Latin America, and Ukraine, where he was head of mission for Triangle Génération Humanitaire until February 2026. The Department of Seine–Saint-Denis remains the main support of the CPLJ-93, with about 1.4 million euros allocated for a total budget close to 5 million. The last public departmental deliberation found allows checking the order of magnitude: in 2024, 1.37 million euros was allocated to the association for its operation. Other aids are partly attached to actions carried out on the ground and can therefore evolve with them. Resources from patronage and the endowment fund developed in recent years are also added. The total free access to the Fair was already in effect in 2025, with the edition welcoming 196,000 visitors. The Department is also presented as the main partner of the event, which it co-produces. The 42nd edition will have the theme "At the Boundaries of Reality," with a question posed by the SLPJ itself: how fiction "draws, untangles and transcends reality"? The new director intends to question "the fabrication of reality, or its deformation."
