Most of Libera's lyrics come from traditional hymns, the Latin Rite liturgy, and contemporary songs by artists ranging from Brian Wilson and Billy Joel to Enya. However, lyrics from various poems and original lyrics are also used. For example, "We are the Lost" uses the poems "In Flanders Fields" by John McCrae and "For the Fallen" by Laurence Binyon, along with a single stanza from the English hymn, "O God, Our Help in Ages Past" by Isaac Watts. While most of the Libera's original lyrics are written by Robert Prizeman, other individuals, including former Libera soloist Steven Geraghty, have also contributed new lyrics to recent albums.
