Call numbers for scores may often be most useful if the opus number or similar designation is added. If all of the Paganini op.1 caprices have the same cutter of .P34, then the op.1 addition will distinguish thsse scores from the op.2 (if that exists). If it is only the sheet music of one caprice, then add the number of the caprice after the opus. This puts all of the op.1 caprices on the shelf together, no matter the edition. If there are many editions expected, then additional ones may have an extra digit in the cutter or an additional cutter by edition (Peters, Kalmus, etc.)

Example: MT265.P34 op.1 (entire op. 1)

Example: MT265.P34 op.1 no.1 (just the first caprice in op.1
