Simple utility to convert links in any file to permanent links via the webarchive.org
**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 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.
## How stop link rot
Link rot can be combated in several ways.
1. Use a [digital object identifier](http://www.doi.org/) which provides persistent and actionable identification. The a website under a DOI changes, it can be changed in the DOI service so that the unique DOI identifier always links to the most up-to-date material.
2. Use a [permanent web framework](http://ipfs.io/). Our current web protocol has many nodes of failure, while newer hypermedia frameworks seek a more distributed protocol with builtin content identies that would allow data to permanently be available.
3. Only link to archiving sites like the [Internet Archive](https://archive.org/web/) or [perma.cc](https://perma.cc/). **My little program I've written helps to combat link rot by providing a simple and easy way to convert all your links to an archived link.**
