I don’t have a link, but I believe theres a tract here on Catholic Answers that addresses that.
Basically, Catholic Bibles have the 7 deuterocanonical books in the OT, plus additions to Esther and Daniel. These Scriptures were originally written in Greek, while the rest of the OT was written in Hebrew. Martin Luther removed them from the body of the OT and put them “in the back”, so to speak, mostly because he disagreed with some Catholic doctrines that sprang from them. Later reformers removed them altogether, and call them the “apocrypha”. The books are Tobit, Judith, Wisdom, Sirach, Baruch, and 1 & 2 Maccabees (plus the additions to Esther and Danile as previously noted). Catholic and Protestant New Testaments are identical.
There’s a neat little book (small but very meaty) called “Where We Got The Bible: Our Debt To The Catholic Church” by Henry Graham that addresses the origins of Scripture and the differences in Catholic and Protestant Bibles. There’s also a book called “Why Catholic Bibles Are Bigger”, but I can’t remember the author right now.
Hope that helped some.
