The first edition of this reference work, called the Catholic Encyclopedia , was published around the turn of the 20th century, with the last revised edition appearing in 1967. This new edition includes the best of the previous entries - many completely revised and updated - as well as new entries, written by subject experts, covering the latest topics of interest. Many thousands of articles are biographical profiles of the people who make up the history of the Catholic Church. Among the 12,000 entries in the encyclopedia are articles on theology, philosophy, history, literary figures, saints, musicians and much more. The articles address questions such as: What impact did Catholicism have on Shakespeare? What role does music play in religious worship? Why is the fish a Christian symbol? What did John Paul II have to do with the fall of Communism in Eastern Europe? What’s the difference between the Catholic and Protestant bibles?
