The Sphere Knowledge System Evolution and the Shared Scientific Identity of Europe


Nineteen people work at the project The Sphere. Knowledge System Evolution and the Shared Scientific Identity of Europe, based in five different areas located at the level of institute infrastructure (Communication, IT, and Library) and the research unit of Department I at the Max Planck Institute for the History of Science.

The first area concerns the historical research; the second, the development of Digital Humanities tools; the third the acquisition of the historical sources, of which the corpus is constituted; the fourth the presentation and the digital output of the project, and the fifth support concerning the production and cleaning of metadata as well as bibliographic research and acquisition of necessary secondary literature.
