Moretti and Sorrento refers to a thematic catalogue of the works of Niccolò Paganini.
The catalogue was commissioned in 1982 by the city of Genoa in celebration of the bicentenary of Paganini's birth.
[1] It was edited by Maria Rosa Moretti and Anna Sorrento, hence the abbreviation "MS" is assigned to Paganini's catalogued works.
