A new edition of the 856 fragmentary historians that comprise F. Jacoby's monumental Die Fragmente der griechischen Historiker Parts I-III, but with significant additions. Each author has a Greek text (updated from that of Jacoby where relevant); facing English translation; new, critical commentary (for the first time for authors 608-856, on which Jacoby did not write commentaries); a brief encyclopaedia-style entry about his life, works, importance, etc.; and a select bibliography. This resource is also known as Brill's New Jacoby.
