Ökonomisches Denken im historischen Rückblick :
Résumé
The end of the 20th century was marked on the one hand by the explosion of economic documents and on the other hand by the appearance of the Internet and the development of the digitisation of writings. These trends have important consequences for the history of economics: whereas an important task was previously the discovery of unpublished documents or drafts likely to shed light on the genesis of a work, in the future the corpus will be broader but also more ephemeral. The historian of economic thought will have to identify the main lines of an exponentially growing corpus, but at the same time he will have to find correspondences with all the scientific or literary productions that have also been digitized by using textual data analysis.
