help! web statistics...

[Nina McHale]

Library director needs stats for presentation, fast! Can anyone 
recommend current resources that would answer:

1. How much of the publicly accessible Internet is searchable by search 
engines? 

2. What is the life expectancy of a URL?

Please reply to me and my colleague Karen O'Connell (kho at georgetown.edu).
