" Papa organized his books neither alphabetically nor by theme, nor by author nor genre, but by their size and color. The books had to look lovely lined up on the shelves, and he collected them avidly, he bought cases of them wholesale, because they went well together, because they harmonized elegantly, like the entirety of the Soleil collection, those gorgeous hardcover volumes bound in solid-colored canvas, and about which Gallimard, in their promotional leaflet, says: as the sun is the pride of the planets, the books in this collection, all in octavo format, will be the pride of your home library. "

― Violaine Huisman , The Book of Mother
