The aim of this course is to provide to students both theoretical and methodological tools for a better understanding of computer science and computational tools, especially with regard to modeling skills, the main cause of the changes that have occurred in the production and dissemination of information, together with the wide spread of telematic networks in recent years. For this reason, it will be analyzed in detail how the traditional analogical modalities, in particular the book object on the one hand and cognitive environments such as libraries and archives on the other, have been 're-mediated' computationally and telematically, in order to provide at the same time an almost ubiquitous access to the historical-documental heritage, together with new forms of analysis and visualization.
