Link rot is an informal term used to describe hyperlinks that no longer point to content on a website, resulting in broken links. This can occur when a linked site's content is moved or removed. =Advice for contributors when adding links= ==External Links== Avoid Deep Linking: try to link to the highest reasonable level of a website and describe the site well enough that should the link need updating one could easily use an internet search to find the correct page. If a specific document is needed, you can provide both a link to the document and also within the description box link to the top level of the website. ==Links in References== References refer to material that was available at the time that the document was edited. Consider linking to cached version of a document via a service such as the [http://archive.org/ Internet Archive] or [http://Archive.is Archive.is] or include a [http://www.doi.org/ DOI] or, if available, link to the relevant [http://webcitation.org/ WebCite] reference (for some academic sources). Always include information about the document so that a reader interested in finding the source can do so, even if the link is no longer available.
