Nietzsche's Features attempts "to collect ALL files we can find on the web, in English, that are directly related to Nietzsche's works, and archive them in what has become the Nietzsche's Features website."
In the About section of they site they bemoan "the experience we had over the last years that although several individuals invested a lot of time and effort in creating Nietzsche pages, after a while they somehow seemed to disappear from the web ... Of course that resulted in a lot of dead links and lost files." Sadly, I don't think the Nietzsche's Features folks have carried on with their good work ... The site was last updated January 1st, 2002. Still, full texts of a number of publications from The Birth Of Tragedy to The Will to Power make this a useful resource.
