This PDF was digitized by Google, as can be seen by comparing page 3 of the PDF with page 7 of the original PDF by Google: both have the right margin chopped off exactly in the same way. An excellent cleaning work was done on it, but in spite of that shouldn't the attribution be properly given? —Carlos (talk) 03:36, 17 February 2010 (UTC)
But you cleaned the pages and put them in the correct order; this should also be cited somewhere on the page... —Carlos (talk) 00:18, 18 February 2010 (UTC)
I have added a new scan of the piano part. It isn't totally perfect, but includes the missing areas of the first scan.
