Let readers know where you found the information

Telling people where the information and facts that are put into articles comes from is an important part of Wikipedia. You should add a citation for the sources of information. To make a citation, or cite a fact means to quote by example, to give authority, and to provide proof.[1] This helps to make sure the facts are right and can be verified (checked to make sure that the information comes from somewhere and so is true) by the readers.

If someone sees that there is information in an article that does not have a source, then the information may be removed. If you see information that needs proof, tag the information with {{Fact|{{subst:DATE}}}}.

The sources used should be trustworthy and from a reliable source. The information should be distributed by a special group that is well-known for checking their own facts as well, making sure the information is correct or true.

On the article page, you should list in numerical order where the facts come from in a section called "References".

If you use citations inside the article paragraphs (this is preferred), then you need to set up the article references section with

== References ==

In line citations use tags in the form of <ref> reference information here </ref> .


Using templates to format citations makes sure that the information in the citation is complete and useful to the reader. Three commonly used citation templates are {{Cite web}}, {{Cite book}} and {{Cite news}}. Click on them to see the full details of all the information that can be included. There are many other citation templates. See the list at Citation templates.

Common templates

The mostly commonly used parameters to use an inline citation with the {{Cite web}} template (using the current date) are:

<ref>{{cite web |url= |title= |accessdate=2020-10-30 |last= |first= |coauthors= |date= |format= |work= |publisher= |pages= |quote= }}</ref>

The most commonly used parameters to use an inline citation with the {{Cite book}} are:

<ref>{{cite book |title= |last= |first= |authorlink= |coauthors= |year= |publisher= |location= |isbn= |pages= |url= |accessdate= }}</ref>

The most commonly used parameters to use an inline citation with the {{Cite news}} are:

<ref>{{cite news |title= |first= |last= |newspaper= |date= |url= |accessdate= }}</ref>

Using refToolbar

RefToolbar is a gadget which adds common citation templates to your editing toolbox. Wikipedia:RefToolbar has a how to install and use guide.

If you are using the Firefox web browser, then there is an add-on called Cite4Wiki that will automatically make citations for web pages. Full details can be found at Wikipedia:Cite4Wiki.

When quoting someone

You should always add a reference when quoting published material. You should always include the page number if there is one. The reference should be placed either right after the quotation

Example: "This is a quotation".[1]

or after a sentence or expression that introduces the quotation.

Example: Jane Austen spoke of novels as follows:[2]

Some statements are from reliable sources. However, they are different from one another. When this happens, the text should clearly say where the opinions came from.

Example: Martin Davis has described some of Burgin's claims as "misleading".[2]

When writing about living persons


Statements about living persons should be sourced very carefully. This is important for legal and ethical reasons. If there is a statement that a living person did something bad, it must cite a reliable source. If you find unsourced or poorly sourced material like this about a living person, whether in an article or on a talk page, remove it immediately! Do not leave it in the article while you request a source. Do not move it to the talk page. Wikipedia articles about people (biographies) or any other materials follow this rule.

Circular sourcing


Sometimes, other people (and books and websites) copy from Wikipedia. This means that the source cannot be trusted to support statements in articles, because it could create "circular" sourcing. We depend on sources to check their facts; using a source which is based on Wikipedia will bypass that check. There can also be copyright problems. Do not use sources which copied their information from Wikipedia. Also, do not use Wikipedia itself (in any language) as a source.
