The Internet is an ephemeral medium that makes it difficult to find “out-of-date” content. News articles may or may not be retained, or may not be organized for ease of access. Businesses and organizations may change names, shutdown, and/or simply delete their websites causing broken links and 404 errors.
The same can be said for institutional websites, such as the Columbia University Irving Medical Center, where non-print published information shared on University websites may seem to disappear. For example, to locate a list of faculty from ten years ago in the Heilbrunn Department of Population & Family Health or a list of Columbia Department of Ophthalmology consultants in 2002, the current websites will not be useful.
However, you can find these older websites by following the search strategies outlined in the Columbia University Web Archive to retrieve this information.
You can also learn how to capture websites that are important to yourself, but which are not yet saved by the Internet Archive or other services.
