|This page documents an English Wikipedia content guideline.|
|This page in a nutshell: External links in an article can be helpful to the reader, but they should be kept minimal, meritable, and directly relevant to the article.|
Wikipedia articles may include external links, links to web pages outside Wikipedia. External links normally should not be placed in the body of an article. All external links must conform to certain formatting restrictions.
Some acceptable external links include those that contain further research that is accurate and on-topic, information that could not be added to the article for reasons such as copyright or amount of detail, or other meaningful, relevant content that is not suitable for inclusion in an article for reasons unrelated to its accuracy.
Some high-value external links are welcome (see § What can normally be linked). However, the External links section should not become a lengthy or comprehensive list of external links related to each topic. No page should be linked from a Wikipedia article unless its inclusion is justifiable according to this guideline and common sense. The burden of providing this justification is on the person who wants to include an external link.
If the website or page to which you want to link includes information that is not yet a part of the article, consider using it as a source for the article, and citing it. Guidelines for sourcing, which include external links used as citations, are discussed at Wikipedia:Reliable sources and Wikipedia:Citing sources.
