I'm not sure exactly why, but I do know that after a lot of discussion and thought with Theta officers, she was given access to the Theta archives and officers/staff. Perhaps (and this is just an out-loud guess), she pursued several of the groups and was given access first (or only) by Theta?

I also know that our archives are quite extensive and wonderfully organized. Not sure if that was a factor or not, since I don't know how robust the other groups' archives are of those early years.
