If you are referring to our scans of Christophori Moralis Hyspanlensis, Missarum liber primus
, these were taken from microfilm (see our http://hdl.handle.net/1802/21916
). Take a look at these files and if you can identify which of the 6 pdfs contains the error we can see if the problem was in the microfilming or in our copy. What and how items are culled from our digital scores collection and added to IMSLP is out of our control, but there's a problem with our initial scans we're happy to try to fix it.
