From 1990, the sprouting of the Internet brings the questions of the field of YOU for the Arquivologia. As the digital documents could be considered how much to the authenticity and originalidade. YOU it brought the transposition of documents in paper for the ones for new supports, electronic. Therefore, the professionals of Arquivologia had had that to argue on the problems of analysis of the criteria of authenticity, trustworthiness or fidedignidade and completude of the form in electronic documents. The object of the Arquivologia is the document of archive and, inside of it, the Diplomatics, whose object is in the study of the structure of the form.

Thus, on this technology, those that will not have adequate procedures of use, conservation and evaluation they would be lost for the fragility of the support and obsolescence of software and the hardware. The Arquivologia, when sharing projects interdisciplinares, makes interface, and has the necessity of if making to interdisciplinar with other sciences, as YOU.
