Daphnet, the ILIESI’s Digital Archives of PHilosophical Texts on the NET, is a portal that provides access to digital platforms dedicated to relevant authors and texts belonging to the history of scientific and philosophical thought. The platforms are characterized by some common aspects: They primarily aim at giving access to primary sources, which in a number of cases are complemented by secondary sources and critical instruments; they can include both facsimiles and transcriptions of manuscripts and printed texts; they are based on open-source programmes and standard encoding (i.e. html, XLM,...); the text of the platforms can be semantically enriched. Moreover, the platforms are interoperable, open to the collaboration of the scholars, and they are certified by a board of reviewers. Principal editor, Antonio Lamarra.
