The Internet Archive serves as, among other things, a repository for webpages. Lawyers (especially), historians (always), librarians (of course), and everyone else can save their webpages to the Internet Archive’s Wayback Machine. (Ue their Save Link Now box.)
I save many of URLs I link to in my blog posts and am frequently astounded to find that too few of those URLs have been saved to the Internet Archive’s Wayback Machine. These government, nonprofit, NGO, official document, and other URLs should be preserved in the Archive.
If you build, update, rely on website content, please SAVE the URL to the Internet Archive Wayback Machine. Websites come and go and you never know when you might need to reconstruct, recall, provide evidence based on, or otherwise want to view a retrospective snapshot of a particular website.
