I have also used the Berthold Rosenthal documents available online from the Leo Baeck Institute. I have also noticed this document available from Family Search which looks like it could be a copy of the microfilm held in the Generallandesarchiv Karlsruhe. David, could you confirm ?
Unfortunately the document is hard to use because of the way it is assembled. First, all left pages, then all right pages.
Also, I read on one of the old Jewish Gen forums that there were two documents : one in 1809 and one in 1815 and that Berthold Rosenthal only copied the 1809.
