Is downloading sheet music from http://imslp.org/ allowed on the Smith network?
imslp.org (The International Music Score Library Project) calls itself a “virtual library of public domain music scores.” Public domain means that the work cannot be claimed as property of any individual or group. In general, this means that anyone can use the material (for commercial or non-commercial purposes). So, assuming the ISMLP is what it purports to be, download away!
