I was working at the main library in a California university preparing our group for Y2K.
I told the staff months before January 2000 that there was not going to be a disaster but some surprises could crop up. (Already many institutions had to work with 4 digit entry issues and that was not a secret), so the free emergency kit given away in the Y2K meeting was given away by me telling the winner to use it to prepare for an earthquake, not for any Y2K event.
Sure enough, it turned that our upgrade schedule was not 100% made, one computer in a department did go haywire because it could not process the 4 date digit entry, the staff member got the only gift given to the one that caught the Y2K bug: a Dilbert plush.
After we replaced the computer the hardware issue was completed, unfortunately my department had to continue for a few months more using an outdated email system that could not process the new dates, but we managed to continue by ignoring the header date information.
So the Y2K was an issue, but it was not as bad as some feared.
