One of the first decisions we faced in scoping out this project was this: which Greek text should we use?

There were essentially four options on the table:

1. H. B. Swete’s ‘smaller’ Cambridge edition from the late 1800s–early 1900s
2. Brooke/McLean/Thackeray’s ‘larger’ Cambridge critical edition
3. The semi-critical Septuaginta edited by Alfred Rahlfs and revised by Robert Hanhart (a.k.a. Rahlfs-Hanhart)
4. The Göttingen critical edition

The first option is in the public domain and available electronically (e.g., here), which was a plus, but all agree it has been supplanted by others. The second option is also publically available (e.g., here) but unfortunately the original project was never completed.
