That was the problem. I set Metadata Management to Automatic, connected the Glo, let Calibre synch up, then ejected. All the series data was there. I love it.
Thank you, thank you, thank you.
I will do my best to track down the bad book that seems to be screwing things up. Since it's my wife's library it's quite a bit smaller than mine, so that will help narrow it down.
Thanks again for all your help.
