One of the purposes of the garethleyshon.info is to make available resources of use to practitioners of Roman Catholic liturgy – priests, deacons and laity. The master index is below. Some of the documents available here incorporate texts from official sources. Users should be aware of the stated restrictions on copyright. My intention here is to make available texts which liturgy practitioners would otherwise have to retype in order to use them in accord with the stated restrictions, or to fill lacunae where there is no current official liturgy published.
