There are a quadzillion websites memorializing the attacks of Sept. 11, 2001. Out of all that, I would recommend visiting the Library of Congress pages first. They have so many, the simplest way to maneuver is to do an Advanced Search on Google (or another search engine that allows you to specify the domain):
september 11 site:www.loc.gov
Is the search I entered. They have a wonderful collection, as you might expect. Very touching. They do have a link page and search engine, which can be accessed at
The thing I learned on Sept. 11 is that life is very fragile; don't ever leave your friends or loved ones without telling them you love them.
