Why is there a distinction between information and communication? More precisely, is information a discipline mostly concerned with machines, tools, engineering? Based on the analysis of the congress proceedings of the French Society for Information and Communication Science (SFSIC), we shall contest this viewpoint. Among the documents examined we have concentrated on papers concerning technologies and machines. This particular topic brings to light the question of how information and communication are linked in France, and that of the cohesion of the discipline. It forms a sort of junction of our scientific constructions.
