There are also many different Catholic translations of the Bible used by different Catholics and Catholic Churches depending on which country you are in. The Catholic Church in the United States uses the New American Bible as its translation for the Mass. Canada uses the New Revised Standard Version in its Mass. The U.K. was using the Jerusalem Bible, but I heard awhile ago that they were also thinking of switching over to the New Revised Standard Version. As for individual Catholics, more traditional Catholics prefer the Douay-Rheims Version (which uses older English like the KJV), The Revised Standard Version Catholic Edition is popular with many people on this site (it is used by the Vatican at times when they are using English quotes from the Bible. The New American Bible is probably the best selling Bible in the United States (because it is used in the Mass), the New Revised Standard Version is used in many of the Universities and is popular with many scholars. The Jerusalem/ New Jerusalem Bibles are popular because the reading flow better and are easier to understand. And there others like the Christian Community Bible which has much smaller sales in the United States but is more popular in South American countries (and is popular in Spanish).
