The first volume of the general catalogue of the artist's work is dedicated to the igloos and based on the exhaustive research conducted by art historian Maddalena Disch, edited by the Fondazione Merz with the support of the Scientific Committee composed of Richard Flood (independent curator and essayist), Frances Morris (Director of the Tate Modern in London) and Vicente Todolì (Artistic Advisor HangarBicocca in Milan) and the Merz Archive. The volume is introduced by a text signed by the Scientific Committee 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; a section of the volume will be devoted to an anthology of texts by the artist and excerpts from interviews concerning the works included in the volume. The book of over 500 pages will be published in two editions, one in Italian and one in English. Publication is planned for Autumn 2023 to mark the 20th anniversary of the artist's death in Milan on November 9th 2003.
