I created (and uploaded files from Sibley): http://imslp.org/wiki/Category:Yafil%2C ... ibn_Chebab
The page that already existed (with files from Sibley) is: http://imslp.org/wiki/Category:Yafil%2C_Edmond-Nathan
The information on the pages I created is more accurate (it contains everything the earlier pages have and more). Clearly one or the other needs to go.
My apologies for making the mistake. I didn't realize the composer was already there.
