HMS Rewind: Harvard Medical School 1997
For those of us born before 1990, it may be hard to remember just how recent a development the web is. The Wayback Machine however provides a remarkable glimpse into how far we have come. Contrast this 1997 Harvard Medical School site with this one. Of course, if you are entering the class of 2011, the World Wide Web has always been an online tool. For these students, the preservation of digital content is taken for granted but with exceptions such as the Internet Archive (which depends on philanthropy and grants) huge tracts of this content are dissolving irretrievably.
