The Egyptian predynastic collection of the National Museum of Archaeology (MAN), including several thousand objects from the Palaeolithic to the Thinite dynasties, has been collecting the fruits of many gifts since the establishment was founded. However, it was the pre-and protodynastic Egyptian collections donated in 1909 and 1910 by the brothers Henri and Jacques de Morgan that prompted the creation of the comparison room and still constitute one of its main components. Inspired by experiments conducted in France and abroad, the study and re-evaluation of the collection – currently still in progress, try to show the interest, both from the historiographic and scientific point of view. The progress of the computerization of the collection and the 2D and 3D digitization of a significant part of the corpus prompted the MAN to disseminate the first results through the digital collection Grands sites archéologiques of the Ministry of Culture, hosted by the MAN. Within this framework, a portal «Jacques de Morgan» is organized according to the main axes of his fieldwork and a chapter dedicated to the re-evaluation of his research. This tool, with variable geometry, aims first of all to make it easier for the widest public to access a first level of data and then to store and exploit scientific information. It is expected to develop in a collaborative spirit and possibly serve as a gateway to other partners and heritage institutions.
