This book describes a new model for digital editions of historical fragmentary texts, i.e. texts that have been lost in their original form and survive only through citations and reuses in later works. This book describes the current state of digital libraries of fragmentary texts and presents two new related projects: the “Digital Fragmenta Historicorum Graecorum” project, which is the digital and expanded version of the Fragmenta Historicorum Graecorum (FHG), and the “Digital Athenaeus” project, which provides an inventory of authors and works cited in the Deipnosophists of Athenaeus of Naucratis with a data model for their identification and analysis.
