was no book, which was kind of a shock." He has since helped to rectify this gap with exhibitions on curating and a book entitled A Brief History of Curating. This volume, which is part of Obrist's Interviews project (see above) compiles interviews from some of the leading curators of the 20th century. While the history of exhibitions has started, in this last decade, to be examined more in depth, what remains largely unexplored are the ties that interconnected manifestations have created among curators, institutions, and artists. For this reason, Obrist's conversations go beyond stressing the remarkable achievements of a few individuals...Obrist's collected volume pieces together "a patchwork of fragments," underlining a network of relationships within the art. In keeping with his desire to explore the world of art and view it as an open system, Obrist has long advocated a participatory model for his activities. One early project, 1997's "do it", is an ongoing exhibition that consists of instructions set out by artists for anyone to follow. In his introduction to the project, Obrist notes that "do it stems from an open exhibition model, and exhibition in progress. Individual instructions can open empty spaces for occupation and invoke possibilities for the interpretations and rephrasing of artworks in a totally free manner. do it effects interpretations based on location, and calls for a dovetailing of local structures with the artworks themselves. The diverse cities in which do it takes place actively construct the artwork context and endow it with their individual marks or distinctions."(sic) In 2003, Obrist curated "Utopia Station" (a section of the Venice Biennale) and was briefly interviewed about the project in Sarah Thornton's Seven Days in the Art World. In 2007, Obrist co-curated Il Tempo del Postino with Philippe Parreno for the Manchester International Festival, also presented at Art Basel, 2009, organised by Fondation Beyeler and Theater Basel. In the same year, the Van Alen Institute awarded him the New York Prize Senior Fellowship for 2007–2008. In 2008 he curated Everstill at the Lorca House in Granada. More recently, Obrist initiated a series of "marathons", a series of public events he conceived in Stuttgart in 2005. The first in the Serpentine series, the Interview Marathon in 2006, involved interviews with leading figures in contemporary culture over 24 hours, conducted by Obrist and architect Rem Koolhaas. This was followed by the Experiment Marathon, conceived by Obrist and artist
