The aim of this paper is to show the permeability of the colonial archive at the written culture of the River Plate along the XIXth century. This has been done over the compilation ot the colonial archive and its diverse lectures at editorial works in press as well as in fiction. The colonial archive was a dispositive of historical and cultural resignifications from the Telégrafo Mercantil up to the publication in the format of feuilleton of the first historic novels, from Pedro de Angelis's Colección to its incorporation in the histories of Litterature. A brief analysis of the colonial archive is proposed focusing on cultural magazines and fictions, through its relation with the viceroyal period and its contribution to the construction of the simbolic imaginary.
