love being able to access this online, for when I am on the road and without my paper copy. Also helpful to assign the 1st etude to a student and print that so they have it, while they decide how to purchase their own copy. However the re-numbering of #1 as #42 took awhile to get used to!
I would love to see the Wohlfahrt etudes on this site, too, for the same reasons. Many thanks to VSM!
