Further thanks to Jonathan Kiel (via Brian Davidson) for passing along Miles Van Pelt’s Göttingen Septuagint siglia chart PDF.
Abram K-J is reviewing Logos’s electronic edition of the Göttingen Septuagint, and he asked if I had created or come across any aids for those trying to read the cryptic Göttingen apparatus for the first time.
This pdf was created by Miles Van Pelt and is posted here with permission. It is a brief list of common symbols and abbreviations used in the apparatus. Thanks to Jonathan Kiel for showing me this last year in our Septuagint seminar.
