Again, for clarification: this is the archive which contains copies of all those other web pages?
Should they have waited to start this archive, which is important enough for you to worry about its future existence, until the law on the right to make copies of websites was settled law? Bearing in mind that there are ongoing lawsuits and discussion on this topic right now, over fifty years since the emergence of the digital networks that rely on making copies to disseminate information.
Do you think that there was an open-and-shut case for an online archive in 1996?
