This typographic style guide provides information on the technical and visual development of 99 different typefaces, functioning as a useful tool to make choice easier and more discriminating. The basic task of the book typographer is to present a text in its clearest and most appropriate form. While display faces can be rich in character, book typefaces must be transparent, allowing the reader to hear the author’s voice without distortion or interference. Book developed for the “Babel on Demand” collection, an artistic and editorial project by Étienne Hervy and Émilie Lamy as part of the 23rd International Poster and Graphic Design Festival of Chaumont.
