If you'll recall, Patti, quite a while ago they chose a Robservations Archivist (I think that was the title). With all of the other problems and things going on, I assume they never got around to setting that up, but I'm sure the intention is to eventually have the full thing here.
I'm also guessing that once all this other stuff is over (will it ever be over?), that MB will go back to illustrating the ones that haven't been.
