Below are some useful links to work being done on the Latin Josephus:

The Latin Josephus Project

(Richard Pollard et al., UQAM) Offers a transcription of the Latin versions of Flavius Josephus' two largest works, the Jewish War and the Antiquities, based on a Carolingian manuscript (Bamberg Msc.Class.78) from the mid 9th century, with parallel Greek and English texts.

"Josephus Latinus - Schritte zu einer Neuedition"

(Reinhold Glei and Randolf Lukas, Bochum) A DFG Project aiming working to produce critical editions of those portions of the Josephus Latinus not published since the 16th century.
