This classic work, previously edited by Ronald Jasper and Geoffrey Cuming, has been a staple source in teaching liturgy to generations of students in colleges, seminaries, and universities. It has now been comprehensively revised for future generations of liturgical scholars.
Updates include:

• New introductions that take into account the substantial changes in recent scholarship
• New groupings of the various prayers into liturgical "families" in order to make their relationships clearer
• Plus, new bibliographies
