|The Institutio Generalis Missalis Romani (IGRM) is the principle collection
of liturgical norms applying to the Mass.
Together with the rubrics (red-lettered instructions)
interspersed throughout the liturgical texts of the Missal, they guide the
priest in the lawful celebration of the Eucharist. In English the
IGRM is called the General Instruction of the Roman Missal
The Institutio Generalis, or its translation, is
printed in the front of the Missale Romanum (the
official Roman Missal) and the approved vernacular
translations of the Missal. The present Institutio Generalis was promulgated in March 2002 as part
of the 3rd typical edition of the Missale Romanum. The
previous two editions were published in 1969 and 1975. The
present English translation, the General Instruction of the
Roman Missal, was adapted by the United States Conference of
Catholic Bishops (USCCB) for the US, and confirmed by the
Holy See on March 17, 2003. It was
promulgated by Bishop Wilton Gregory, then President of the USCCB, on March 19th, 2003, as "effective immediately."
At this time, February 2005, the translation and approval of
the 3rd typical edition of the Missale Romanum for use in
the English speaking countries is not yet complete. However, the
GIRM has been separately published by the USCCB and is available
Religious Catalogue (item 5543), as is the 2004 Roman document
on liturgical abuses Redemptionis sacramentum (item 5619).
There is also a program which aired on EWTN explaining some of the
norms (item HVGIRM).
The copyrighted text of the GIRM with the American adaptations
can be viewed on the website of the United States Conference of
