The complete system of knowledge is a standard trope of science fiction, a techno-utopian dream and an aesthetic ideal. It is Solomon’s House, the Encyclopaedia and the Museum. It is also an ideology – of Enlightenment, High Modernism and absolute governance. Far from ending the dream of a total archive, 20th-century positivist rationality brought it ever closer. From Paul Otlet’s ‘Mundaneum’ to Mass-Observation, from the Unity of Science movement to Wikipedia, the dream of universal knowledge dies hard. As a political (...) tool, the total archive encompasses population statistics, gross domestic product, indices of the Standard of Living and the international ideology of the United Nations Educational, Scientific and Cultural Organization, the World Health Organization, the free market and, most recently, Big Data. Questions of the total archive engage key issues in the philosophy of classification, the poetics of the universal, the ideology of surveillance and the technologies of information retrieval. What are the social structures and political dynamics required to sustain total archives, and what are the temporalities implied by such projects? This introduction and the articles that follow describe and place in historical context a series of concrete instances of totality. Our analysis is arranged according to four central themes: the relationship between the Archive (singular) and archives (plural); the image of the archive and the aesthetics of totality; pathologies of accumulation; and the specific historical trajectory of the total archive in the 19th and 20th centuries.
