NRSV w the deuterocanonical books

[jas84173]

Can someone explain to me why there are additional books in this Bible as more than even Catholic Bibles? I believe it says the Eastern Orthodox view these scripture entirely or somewhat?
The books are
1 Esdras
Prayer of Manesseh
Psalm 151
3 Maccabees
2 Esdras
4 Maccabees

I believe that the Orthodox Old Testament uses the whole Septuagint text. This article might help:
