Notations: Diagrams & Sequences, by Bernard Tschumi.Artifice Books, August 2014, 304 pages, $40.

An extensive collection of previously unpublished drawings, this book is beautifully bound in a red cloth cover, Tschumi’s signature color. It presents the conceptual “notations” behind a range of projects, arranged chronologically, from the Parc de la Villette in Paris to the New Acropolis Museum in Athens. Tschumi’s expressive drawings, sketches, and diagrams help us understand his design process and how “drawing is thinking” for him.
