Here is the most recent issue of the Sphinx and two back issues of the Legacy. I am sure at some point they'll upload the newest edition of the Sphinx. Sphinx is published bi-annually, although sometimes they run a little behind schedule. Part of the reason why we're running behind schedule is that Diane Macey, CO's coordinator and keeper of almost all information Phi Sig, just retired, and so they're a little focused on replacing her.
I know for a fact that CO is working hard to get the site ready to be updated, including a "sisters only" site - the problem is finding technology to interface with the office systems they are currently using. It's complicated, but trust me, they're working on it.
