This work is the major English-language encyclopedia on Catholic topics. It contains some 17,000 articles, each with a bibliography. Unfortunately many of the articles in the 2003/online edition are reprints from the 1967 edition without any updating. The 1967 edition of the New Catholic Encyclopedia (St Michael's 1st Floor Reference Area BX 841 .N44 1967) and the 1907 edition of the Catholic Encyclopedia (available online; St Michael's 1st Floor Reference Area — BX 841 .C25 1907) include some articles on topics not included in the 2003 edition of the New Catholic Encyclopedia; these works may be particularly useful for some historical topics.

This work is the standard English-language translation of exerpts of papal and conciliar statements arranged by subject. It is the appropiate tool to use when looking for the major magisterial documents on a particular theological topic (e.g. grace). The original language text of each document (usually Greek or Latin) can be found in the Enchiridion symbolorum, first edited by Johannes Denzinger (St Michael's 1st Floor Reference Area — BX 1749 .D415 1999). An older but similar work, The Sources of Catholic Dogma (St Michael's 1st Floor Reference Area — BX 1749 .D413 1957), arranges excerpts of the most important papal and conciliar statements in chronological order.

"A statement of the Church's faith and of catholic doctrine, attested to or illumined by Sacred Scripture, the Apostolic Tradition, and the Church's Magisterium. ... a sure norm for teaching the faith." (John Paul II, Fidei depositum).

[St Michael's 1st Floor Reference Area — BX 1751.2 .O813 1974]
This book is a basic outline of the teachings of the Catholic Church which presents essential statements of doctrine and attempts to explain the foundations of that teaching in Sacred Scripture and Tradition. It is excellent for determining how official a particular teaching is (e.g. de fide or merely the more probable opinion held by most theologians). Since it was published in 1955, it does not include any references to sources from the past fifty years.
