From databases to archaeological online resources: the logic of object classification

Since the 1970s, the development of archaeological databases has characterised the history of archaeological computing. The paper presents a summary of the pivotal early projects, with a particular focus on Italy and France, up to the current projects shared online. They are constantly monitored by the international journal «Archeologia e Calcolatori», that since 1990 is an observatory of theoretical and methodological aspects of computing and information technology applied to archaeology.
