In general, arrangement of music is similar to arrangement of literary writings. A small amount of music or music that is peripheral to the research value of a collection may be included in a series such as Other Papers. If music is extensive or central to the collection’s research value, organize it in one or more dedicated series or subseries. Music by a single composer could be listed alphabetically by work title, medium of performance (e.g. keyboard, voice, orchestra) or type of composition (e.g. operas, string quartets, songs, jazz arrangements). Music by more than one composer could be arranged by composer name and subarranged by work title, medium of performance, or type of composition.
