Gottingen Septuagint LXX

Question

What is the difference between the Logos books LXX-G 12ProphApp I and LXX-G 12ProphApp II?  I thought they were all the notes separated into two volumes, but that is not it.  They appear to cover the same books. Both begin with Hosea, but there are completely different notes for each book.

From Claude:

The Göttingen Septuagint (Septuaginta: Vetus Testamentum Graecum) uses a two-tier critical apparatus in each volume:

Apparatus I — Manuscript Variants

Records variant readings from the Greek manuscript tradition — the different readings found across the various Greek uncials, minuscules, lectionaries, and papyri. This is the primary textual apparatus showing how the Greek text itself varies across witnesses.

Apparatus II — Versional and Patristic Evidence

Records evidence from the ancient versions (Latin, Syriac, Coptic, Armenian, etc.) and quotations from the Church Fathers. This secondary apparatus helps reconstruct the text indirectly, since these sources translated or cited the Septuagint and can preserve readings lost in the Greek manuscripts.
