Tar file of all the circulars (as of a couple minutes after every midnight US EastCoast local time).
This tarfile is a convenient way of getting all the Circulars if you want to 'mine' them for some particular need.
(If you are willing to share, I would appreciate getting a copy (for my own private GCN_Administrater use)
of whatever statistical analyses you derive from your mining.)
