Breviarium S. O. P. blogspot.
This ordo includes a complete calendar of the Dominican Rite liturgical year for 2015. In addition, it includes the collects for the Dominican blesseds who are not on the Dominican general calendar (so that a votive commemoration can be made of their feast), obits of the deceased Masters General, and announcements of days when Lay Dominicans (Dominican Tertiaries) can obtain plenary indulgences.
Finally, it contains an English translation of the Office of Prime, which was omitted from the 1967 English translation of the Dominican Breviary.
It may be ordered from Dominican Liturgy Publications.
