Anna Patterson built a search engine for the Internet Archive's Wayback
Machine! She has indexed a portion of the full archive, 11 billion
pages, and is available now at:

http://web.archive.org/

This search engine has a novel interface that shows hits over time and
also catagories and topic related to the search. Please refer to Anna's
slides that describe how it works:
http://ia00406.archive.org/cobwebsearch.ppt

The Internet Archive will be adding some more machines to this service
and Anna will be changing this beta service based on feedback, so please
use it and post feedback to the forum.


We hope this will be useful to researchers and historians to make the
web's past more accessible. Thank you to Anna!
