The Bavarian State Library provides a number of digitizations of sheet music from its music department. I still didn't have the time to browse them, but I noticed this:
Neusidler, Hans: Ein Newgeordent Kuenstlich Lautenbuch [...] Nürnberg, 1536 here: http://daten.digitale-sammlungen.de/~db/0004/bsb00041542/images/ Can be also downloaded in pdf. M. To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
