The binet TypographiX is sadly only trained in French typography. Thus, this page is only available in French. If reading it still interests you, please use either the button in the top right corner or the link at the bottom of the page to change language. This situation is a great mishap so if you, or anyone you know, is interested in English typography, please contact the binet as fast as possible (the link is on the bottom of the page) so that a proper introduction to English typography can be written.
