Now almost 20 years old, the digital turn in architecture has already gone through several stages and phases. Architectural Design (AD) has captured them all - from folding to cyberspace, nonlinearity and hypersurfaces, from versioning to scripting, emergence, information modelling and parametricism. It has recorded and interpreted the spirit of the times with vivid documentary precision, fostering and often anticipating crucial architectural and theoretical developments. This anthology of AD's most salient articles is chronologically and thematically arranged to provide a complete historical timeline of the recent rise to pre-eminence of computer-based design and production. Mario Carpo provides an astute overview of the recent history of digital design in his comprehensive introductory essay and in his leaders to each original text. A much needed pedagogical and research tool for students and scholars, this synopsis also relates the present state of digitality in architecture to the history and theory of its recent development and trends, and raises issues of crucial importance for the contemporary practice of the design professions.
