From this page you can access archives of email sent out on the logicT125@mind.ucsd.edu mailing list.
The archives are broken up roughly by week in the quarter. Obviously, only links to archives up to the current week will actually go to an existing document. The archives go up to the 13th week in order to accomodate announcements made after the and of the term, such as where exams can be picked up, etc.
