The first volume of the catalogue raisonné of the artist's work is dedicated to igloos. Based on the exhaustive research conducted by art historian Maddalena Disch, it is an editorial project of the Fondazione Merz, with the support of the Scientific and Editorial Committee composed of Mariano Boggia, Luisa Borio, Richard Flood, Beatrice Merz, Frances Morris and Vicente Todolì. The volume is introduced by a text by Beatrice Merz and an essay by Maddalena Disch. Each work is presented with an analytical historical and biographical profile supported by accurate bibliographical references and an exhaustive photographic repertoire.

The volume includes texts by the artist and interviews with Jean-Christophe Ammann, Mirella Bandini, Sergio Barana, Matteo Benvenuti, Achille Bonito Oliva, Germano Celant, Bruno Corà, Danilo Eccher, Corinna Ferrari, Piero Gilardi, Marlis Grüterich, Claudio Guarda, Michael Haerdter, Richard Koshalek, Corrado Levi, Salvatore Licitra, Beatrice Merz, Linda Morris, Fumio Nanjo, Suzanne Pagé, Gabriele Perretta, Bartolomeo Pietromarchi, Mila Pistoi, Barbara Reise, Giuseppe Risso, Harald Szeemann, Laura Tansini, Caroline Tisdall, Tommaso Trini, Paolo Vagheggi, Gemma Vincenzini and Francesco Vincitorio; as well as a biographical note and bibliography edited by the Merz Archive.

The book, consisting of 560 pages and 350 images, is published in two editions, one in Italian and one in English.

The project is realised thanks to the support of the General Directorate for Contemporary Creativity of the Ministry of Culture within the framework of the Italian Council programme (2023).
