Breviary

A breviary (from Latin brevis, 'short' or 'concise') is a liturgical book of the Latin liturgical rites of the Catholic Church containing the public or canonical prayers, hymns, the Psalms, readings, and notations for everyday use, especially by bishops, priests, and deacons in the Divine Office (i.e., at the canonical hours or Liturgy of the Hours, the Christians' daily prayer). The word can also refer to a collection of Christian orders of prayers and readings, such as contained in Anglican or Lutheran resources. In general, the word breviary may be used to refer to an abridged version of any text or a brief account or summary of some subject, but is primarily used to refer to the Catholic liturgical book.
