AA Files #76 is structured as a glossary of terms relevant to contemporary debate in architecture. Each entry has been contributed by a different author, and represents a personal position as much as an attempt to frame the topic in a broader context; morethe issue therefore maps both a landscape of current concerns, interests, and ambitions, and also an overview of diverse positions and forms of practice. The authors of this glossary are practitioners, academics, students, lawyers, politicians, activists, and their contributions do not only seek to explore the potential of the themes put forward, but also to question the ways in which we can discuss space – as designers, as scholars, as citizens.
