The Library of Congress classification for Music is M. This means that the call numbers for books on music will begin with the letter M. Most of the music books in the library are located on the second floor, toward the back of the floor on the right.
Reading Room / Reference Collection
A significant companion music collection is located in the Reading Room (main floor of the library), also classified under M. An example of books in this location would be The new Grove dictionary of music and musicians, which is mentioned in your research paper handout. As you enter the Reading Room, turn to the right. You will find the music books in the free-standing section of shelving.

M Musical Works
