Knusel,
YES, there are the 2 volumes of "JG 300" by Goyat and Lorant:
http://www.amazon.com/300-Wilde-Vol-.../dp/0976103400
I do not remember where I read that, most probably on the book itself, that it took those Historians 25 years of researches and contacts, to finish that work...so a magnificent book, which I fully recommend you.
Yours,
Adriano
