The Manart database gathers data about manifestos produced from the end of the 19th century onwards, in all geographical and artistic areas. Resolutely interdisciplinary, Manart has two long-term objectives: first to make available online facsimiles of manifestos with detailed records scientifically checked; second to allow advanced searches on the manifesto phenomenon. Relating descriptive and analytical information for each entry, the database enables a smooth flow between macro and micro perspectives, i.e. between the history of major evolutions and specific case studies. Manart thus offers a platform for innovating methodology within the highly complex research field of history of art.
