browsers and screen sizes

[Avi Janssen]

Jakob Nielsen argues that users will still be using Netscape version 3 until
early 2001 (http://www.useit.com/alertbox/990418.html).  Does anyone know of
a site that tracks what percentage of users are using what browser?  A
similar question is what percentage of users is using what size/resolution
monitor.
We are designing our library's website, and I'm trying to win a usability
argument.
Thanks,
