Generally speaking piano music for 4 (or more hands) and 2 (or more) pianos have a call number that range between M 200 and M 216. However, there are some compositions in other call numbers and that is why I created the various divisions. Don't forget to check the LibGuide Page, Digitized Sheet Music for online scores.
As you check the lists, you will see some items without a call number. These items are currently on order and when we receive them, I will update the page to show the correct call number.
If you find something else that I have missed, please let me know so that I can add it to the various lists.
