Definition of "dancecard"

[[Episode 1: Telemachus], page 10] Her secrets: old feather fans, tassled dancecards, powdered with musk, a gaud of amber beads in her locked drawer. […] In a onepiece evening frock executed in moonlight blue, a tinsel sylph's diadem on her brow with her dancecard fallen beside her moonblue satin slipper, curves her palm softly, breathing quickly.

1922 February, James Joyce, “[Episode 1: Telemachus]”, in Ulysses, Paris: Shakespeare and Company, […], part I [Telemachia], pages 10 and 423

Our hostess' memorabilia included several of the little dancecards that girls of that time used at parties to dance with boys. All the songs that the band was planning to play were listed, each with a blank line next to it that the dancers needed to fill in to share a song. Many of the songs were scratched out, which our hostess explained maeant that the girl was reserving those songs for her favorite boy of the evening.
