For a long time, the private archives have been considered as a source only useful for the study of the history of nobility. In fact, they represent a pool of information useful for several lines of research.
Since the personal stories of the archive owners are intertwined with episodes of historical and political relevance, there is information relating to great historical events. The archives also catalogue various aspects of local events.
These include the public administration of communities, the development of the local area, and economic activities. Sociological perspectives underlying the dense network of interpersonal and family relationships can be derived from the documents as well.
