For our last afternoon we went to meet Christoph and Teo Schifferli in ARCHIV. According to its members, ARCHIV is «the playground of a few addicted collectors, enjoying remarkable or unusual publications, ephemera, photographs and facts relating to one or all of these». With great enthusiasm, Christoph showed us his little collection of architectural books from the seventies, belonging to a larger collection of art books he has been widening for more than almost thirty years. This presentation oriented the discussion towards the role of the book in architecture, as Kurokawa's book «Capsule» could really be considered as the project per se. We also discussed on the evolution of printing methods in the XXth century, in Europe and in Japan, in the context of the book and the press industry. In addition to that, Christoph had prepared many other art books on the tables. Most of them, such as Christopher Williams' «The production line of happiness» book(s), which ironically deal with the relationship between image, text and context, or Stanley Brown's obsessive minimalistic books, published by different galleries and related to his works about distances. Although some of these books were clearly post-modern, we couldn't really find in this collection of rather recent books the modern books that would have allowed a comparison, although there was a tension between the modernity of the graphic design, and the post-modernity of the book content. We were all stunned by Christopher's (almost unreasonable) passion for such a collection, containing projects and being itself a huge project, of which we had the chance to get an insight.
