The use of the other books ("book of works"?) in Rev 20:11-15 with regards to reward and merit

When I read Rev 20:11-15 to answer [another question](https://christianity.stackexchange.com/a/107604/10672) an idea occurs to me. Maybe there are two books at play in the Great White Throne Judgment, the book of life (criteria for salvation) and what appears to be the "books of works" (title not given), noting the phrase "another book" and the plural form of "books" in v. 12. Here's the CSB translation: > 11 Then I saw a great white throne and one seated on it. Earth and heaven fled from his presence, and no place was found for them. 12 I also saw the dead, the great and the small, standing before the throne, and **books were opened**. **Another book was opened, which is the book of life**, and the dead were judged according to **their works by what was written in the books**. 13 Then the sea gave up the dead that were in it, and death and Hades gave up the dead that were in them; each one was judged according to their works. 14 Death and Hades were thrown into the lake of fire. This is the second death, the lake of fire. 15 And anyone whose name was not found written in the book of life was thrown into the lake of fire. Is it possible that the "book of life" is the criteria of inclusion for going to heaven while the "book of works" (for lack of a better name) is for giving rewards for the "treasures in heaven" (Matt 6:19-21) that one has accumulated while on earth, namely good works out of faith? That the "book of works" contain everything that God sees we do in secret (Matt 6:4) and the unrewarded suffering we do for Christ (Matt 5:10-12)? One is also reminded about Paul talking about how the works of God's servants (who labor in the field of harvest) will be tested by fire (1 Cor 3:10-15). Or is my speculation in the preceding paragraph unwarranted because I'm mixing un-relatable concept of "works" from 3 completely different *genres* (a gospel, an epistle, and an apocalypse)? Am I guilty of reading Matthean / Pauline concepts into Revelation or am I to be applauded for doing ["inductive Bible study"](https://biblestudy.tips/inductive-bible-study/) ? My question: **Compare and contrast Reformed and Catholics view on the role of both books mentioned in the Great White Throne Judgment, especially with regards to "merit" and "reward".** What I'm trying to ascertain: - **For Reformed**: what is the use of the *other* books since it appears that what matters is only whether the names are found in the "book of life"? - **For Catholics**: does the church use the *other* books in connection with the doctrine of good works, **EITHER** with regards to the treasury of merit **OR** with regards to justification by faith and works? **OR BOTH?** *Note*: - For the sake of answerability, I only ask to contrast the Reformed position and the Catholic position as a minimal scoping, although additional position(s) are welcome as a bonus. - To defend that this Q is not opinion-based, I require citations from published Reformed and Catholic theologians.
