Reference works are written by scholars or experts in a particular field. They are a good place to begin your research and to find background information. Some of the various types of reference works include:
The New American Bible, Revised Edition (NABRE) was released in 2011 by the US Congress of Catholic Bishops. The bible is the culmination of nearly 20 years of work by a group of nearly 100 scholars and theologians, including bishops, revisers and editors. The NABRE includes a newly revised translation of the entire Old Testament and the 1986 edition of the New Testament.
The Catechism of the Catholic Church is the work promulgated by Pope John Paul II in 1992 to coincide with the 30th anniversary of the opening of the Second Vatican Council. The Catechism is the official, authoritative, and authentic reference text for teaching and transmitting Catholic doctrine.
