They noticed the World languages section, picture books for young readers, the artwork (the chair) displayed in the library, computers in the research area, classroom for working and even that there is a book for blind people in the library:)
This was the magical "The Black Book of Colors" by Menena Cottin and Rosana Faria laying on a shelf top waiting to be displayed. It is an interesting book "with raised black line drawings, which can be deciphered by touch, accompanied by a beautifully written text which is translated into braille" (from the book jacket).
How does that sound: "... yellow tastes like mustard, but is as soft as a baby chick's feathers" and "Black is the king of all the colors. It is as soft as silk when his mother hugs him and her hair fall in his face". Pretty amazing, doesn't it? Check it out from the library! You might even get a free tour.
