"As early as the second century A.D., "Septuagint" was used as an umbrella term for the Christian collection[s] of Jewish scriptures […] This convenient but potentially misleading use of the term still prevails […] Since there is no homogeneity among the various translation units of this collection […], it is more accurate to speak of the oldest recoverable Greek form of each section/book (OG="Old Greek"), which in the Pentateuch is the LXX proper."

"It is probably better to refer to the original translation of books other than the Pentateuch as the Old Greek (OG) so as to distinguish them from the original translation of the Pentateuch and from the later revisions and new translations. (when referring to these initial translations of the Hebrew Bible as a whole, some scholars prefer the combined abbreviation "LXX/OG" as a continual reminder of the diversity that characterizes the corpus.)
