The third in a 3 volume set of study lectionaries by Harper Collins was actually the first one that I bought. It contains all the readings for the following masses - Ritual Celebrations, Masses for various needs and occasions, Votive Masses and Masses for the dead. Unlike the first two volumes, it is therefore the one that is likely to be used least of all. Nevertheless for one who has a need for a study volume that is laid out in every way like the lectionary that is used at mass, this is an invaluable item. Perfectly and securely bound, with a ribbon to mark out the required page, this will last a lifetime and more.
