Thanks for linking the digitized version. According to the publisher's homepage (You are not allowed to view links. Register or Login to view.), the volumes by C. Gilly are supposed to be published starting in 2040 (!), so it might not be a bad idea to explore the scans beforehand... well, probably the date is not correct, but with none of the volumes published yet and the Widemann catalogues being volume 6, it might take some time. 
Have you tried running it through transcribus or similar software? Due to the sometimes messy handwriting and mix of Latin and German, the results may not be great, but it's worth a try.
