# Prevent Link Rot
**Link rot** is real, it is common, and it is pervasive. What is **link rot**? Link rot is essentially *the process by which hyperlinks cease to function, usually because the web page or server they point to has moved or has become permanently unavailable*. It has existed since the internet began. An example of its influence can be seen as recently as 2000, when [a study](http://dx.doi.org/10.1002/bmb.2003.494031010165) found that within 24 months, 50% of .com domains and 20% of .gov domains were no longer viable.  [Another study](http://dx.doi.org/10.1017/S1472669614000255) found that 70% of links in Harvard Law Review and 50% of links within the United States Supreme Court opinions are no longer viable.  If we are to take the internet as a primary resource seriously, then we seriously need to think about undertaking a better way of long-term preservation of link contents.
