Seth Robertson is the Systems Manager here at the CTR. His interests include Science Fiction and Fantasy, the Disney Afternoon, Opera, Classical Music, and (fortunately for the CTR) computers. Seth's .plan could be of interest to some, while Seth's sorta up to date resume might be of interest to others.
If you have questions or comments, your best bet is to send electronic mail. Reaching him by phone is problematic at best. Problems should be referred to manager@ctr.columbia.edu. seth@ctr.columbia.edu is only for personal mail.
