The National network of Houses for the Social Sciences and Humanities (RnMSH) and its 22 houses (MSH) supports scholars in the social sciences and humanities (SHS), with an emphasis on interdisciplinarity and project-based research. The RnMSH plays an important role in the development and practice of interdisciplinarity, as well as in the structuring research engineering in France. The Houses for the Social Sciences and Humanities are a hub for strong partnerships between universities, research institutions (in particular the national center for scientific research -CNRS) and public bodies. The RnMSH in a few dates : 2006 Creation of the GIS (scientific interest group) – RnMSH, supported by the CNRS and 19 French universities. 2012 Network registered in the roadmap of the Ministry for Higher Education and Research as a research infrastructure in social sciences and humanities (IR), in the domain of scientific and technical information (IST). 2016 RnMSH renewed as a research infrastructure. 2019 Updated RnMSH charter, under the auspices of the CNRS and the Conference of University Presidents (CPU), with the collaboration of MSH and within the framework of the Athena Alliance. 2021 RnMSH renewed as a research infrastructure in social sciences and humanities on the roadmap of the French ministry of scientific research. The national network of Houses for the Social Sciences and Humanities RnMSH brings together five technological platform networks, based in the houses, which develop collaborations with the Very Large Research Infrastructures (IR*) Huma-Num and Progedo and which federate about 50 platforms based on the houses : Spatio: resources for spatial data analysis, imagery and 3D. Scripto: written data, from literary texts to contemporary world archives, including music scores. Audio-visio: audio and visual resources and corpus, from ethnological documentaries to filmed conferences. Cogito: equipment for research in cognitive sciences, and data from these experiments. Data: corpus of quantitative data and quantitatively analyzed data.

4 one year job contracts making investigation about RnMSH platforms networks have been financed by the French ministry of research (Ministère de l'enseignement supérieur et de la recherche). Two permanent research engineers working at RnMSH are employed by CNRS (the French national center of scientific research). French universities finance the houses of social sciences and humanities (MSH) via their staff.
