Sorry to disagree, Ely, but no. Good as the Levy site is for researching so much music that is found nowhere else, the fact is that the images are a dingy gray and hard to read. BUT if the music is also available at Library of Congress, Duke, Brown University, etc., you'll find the images are vastly superior. Just check them out and see for yourself.

I have had some luck downloading Levy images and doing some enhancement to them to make them more legible, but none of that is necessary at Duke. In fact, if you use the large images, you are going to have to reduce them if you plan to print them. As Bill says, the smaller ones are "perfectly usable."
