Open Booksis a project launched by Charlotte Cheetham and Sophie Demay in 2011, exploring the relationship between printed materials and exhibition formats. It unfolds through exhibitions, events, and a publication designed to examine this dynamic interaction. The project began with exhibitions at the Royal College of Art, London, and Cneai (National Art Center for Publishing and Image), Paris. Early volumes, printed as exhibition support media, evolved into catalogues documenting the events. In 2015, additional volumes expanded the research. Volume A-E serves as a hybrid: part catalogue, part archive. Through captions, images, invitations, and metaphorical bookmarks, it bridges book and exhibition, inviting readers to engage with this evolving dialogue.
