Jacoby Online is a digital edition of fragments and testimonia of Greek historians and other authors from antiquity. Although the works of these historians are now lost, we still have passages in the form of citations and paraphrases in ancient texts that are preserved. Jacoby Online is anchored in the work of Felix Jacoby, who started the work of collecting fragments and writing commentaries. To his Die Fragmente der Griechischen Historiker I-III (1923-1959) are added two new editions, Brill's New Jacoby (2006-2021) and Brill's New Jacoby - Second Edition (2016-), both edited by Ian Worthington. Felix Jacoby himself was unable to finish the collection, but in the 1990s, the work on Die Fragmente der Griechischen Historiker resumed, resulting in FGrHist Part IV, currently edited by Stefan Schorn, and FGrHist Part V, currently edited by Hans-Joachim Gehrke and Felix Maier.
