Mediation is systematic and essential for a good understanding of the spirit, and for commitment to an exhibition. It raises awareness of contemporary art, and enables the public to understand the artworks. The dialogue between the artworks conceived by the artistic and scientific project of the exhibition curator, and serves as an educational tool and accompanies the life of the exhibition. Sustaining exhibitions through an exhibition catalogue is essential. The design of these publications is done with care, both in terms of writing and iconography. The same diligence can also be found in biographical, scientific, or the documentary content. These texts carry the same amount of importance as the catalogues, because they inform people about artworks and artists. They are an essential basis for the documentation and promotion of a collection.
