The book SNOWI IS NOT WILLEM is like a manual gathering all the SNOWI images, with their codified references, and showing some examples of uses of the SNOWI image bank.

The comic strips of Mickael Faure, Julien Goeury, Elise Parré, Charles Pennequin and Carine Soyer, the management device as well as the critical propositions of Christophe Kihm, Florence de Méredieu and Joseph Mouton punctuate the book. The SNOWI images are classified by series, and by order.
