The authors, the editors of the Archives Parlementaires (Première série), describe the eventful history of this collection founded a hundred and fifty years ago. At a time of the digitalization of large documentary collections, the authors underscore the highly diversified « periods » of this source compiled by its editors, first by librarians and civil servants of the Chamber of Deputies, then by historians of the French Revolution, concerned as these were, by the uniformity of the series. The authors show how the « colonne vertébrale » of this construction, the report, is of doubtful reliability beginning in Thermidor an II. The analysis of this post-thermidorian construction until the turning point of the months of Brumaire and Frimaire an III marked by its exceptional nature because of the trial of the deputy Carrier, posed an essential epistemological problem in the political construction – unmistakenly partisan.
