Brill's New Pauly is an English translation (with revisions) of the German
Der Neue Pauly which itself is the latest revision of the great multi-volume encyclopedia of the ancient world, known familiarly as
Pauly-Wissowa. This resource in print was known as the
Realencyclopdie der Classischen Altertumswissenschaft begun by August Pauly in 1839, with an expanded edition by Georg Wissowa published between 1890 and 1980. The
New Pauly is still in progress, but includes access to the German edition, which was completed in 2003. The online version, like the print edition, includes two sections: Antiquity and the Classical Tradition.
