Is there a way of searching just the non-canonical books in the Septuagint?
It's matter of using the correct Passage range. If you click All Passages in a Bible Search, you can see the Saved Ranges/Common Divisions for the resource. If none are suitable, they will show you the format to use in the Range Box. Enter your passage ranges in the order they occur in the resource.
e.g.Esdras A-Esdras B;Wisdom of Solomon-Sirach;Judith-Tobit;Baruch-Letter of Jeremiah;Susanna-Odes in LES. But I note that Ezekiel somehow gets included in results, after Letter of Jeremiah. This appears to be a bug, as I can't eliminate it.
EDIT: The Common Division for Major Prophets (Isa-Ezek) is incorrect, as it includes Baruch, Lamentations, and Letter to Jeremiah.
Thanks, Dave. I hadn't thought of working with LES to get the division.
The order and content will be different for other LXX types e.g. Sept for Logos Morph (LXX-R) vs LES (LXX-S)
