Citations and footnotes are essential elements of well-sourced articles. This page covers the different formats used to reference sources on the Lexicanum.


Sourcing is vital. Any article created without proper sourcing will be deleted. Source your articles, and help add references to articles without proper citations!

All sources used must be canon. All official print material can be used as a canon source, although there may be disputes if, for example, a Novel contradicts a current Codex. For old editions, recent editions take precedent, although information from previous editions may be referred to if properly signposted. Accepted sources and any canonicity issues can be found here, and you can always ask the community if you're still unsure!


Sources must be cited by Title, Edition and/or Date, and page number/s. This differs for Novels; only chapter number is required, although a short quotation may also be supplied for clarification.

  • Citations must be added to the end of each paragraph.

Even if there is only one source to an article, you must put a footnote to any and all paragraphs. This is so that if any information is edited or added at a later date then it is clear where the information is from. Further citations can of course be used within the text, but a relevant citation must still be applied at the end of the paragraph.

  • Official sources must be added for any change or addition of information.

Remember to add citations as you add information - this helps anyone editing the article after you, and prevents unnecessary reverts or long discussions about canon. Referring directly to official sources means details won't be misremembered or entered vaguely.

  • It is absolutely compulsory to include page numbers (in the case of novels chapter numbers)!

Referring to the source by name only makes it difficult to verify new information. Checking for the exact source helps ensure you're using references that actually directly support the text. Detailed referencing also assists other users in their research for these or other related articles!

How to add citations

We use the footnote template to link the in-line citation number with the matching footnote (click the number to see this in action).[0] We use {{Fn|#}} for the in-line citation number, and {{Endn|#}} to link to the footnote at the bottom of the page (# is replaced with the footnote number, starting at 1 and running 'til you run out of references). For example:

Paragraph of new text, or statement.[1]


Paragraph of new text, or statement.{{Fn|1}}

This footnote is then referenced under the level two "Sources" heading (i.e. ==Sources==) at the end of the article:


*{{Endn|1}}: [[Codex: Exemplum (Xth Edition)]], p. 71

In practice, it should look a little something like this:

This new text has something to prove. It was founded on the ice-world of Hubbleron in late M29[2] and will have citations at the end of each and every paragraph.[3]

Different formats

The above example covers most print materials permitted as sources on Lexicanum. Some formats, however, have varying page numbers or irregular formats. They can be cited as detailed below.

In the case of novels, no page numbers should be given (they vary between translations and print runs, and will only cause confusion). In this case chapter numbers are compulsory. Chapter names and other divisions (e.g. "Part III") are to be used if that is how the novel is formatted.

Short stories are to be referenced with full title, anthology in which it was published (if applicable), and author. Like novels, page numbers differ between print runs. Unlike novels, short stories don't have chapters to quote.

Audiobooks are referenced in a similar manner to novels, but using track numbers instead of chapter numbers.

Web Site Sourcing

Only official Games Workshop (and subsidiaries) websites should be listed as a source.

PDF files

You cannot link directly to a .pdf document. GW & Lexicanum policies state you must link to the Terms of Use that leads to the .pdf file. And only to .pdf files that are posted on an official GW site.

Active Sites

When citing a web site, use the same process as citing a GW publication. Also include a notation of when you viewed the site using ISO date notation (YYYY.MM.DD).


*{{Endn|12}}: [http://www.armageddon3.com/ Armageddon 3 Web Site] ''(site accessed 2007.02.17)''

Inactive Sites

A website that has been removed should not be listed as a source. However, if a site that had been listed as a source (see above) has been taken down, the citation should be changed as follows:

  1. Remove the link brackets [ ]
  2. Place <nowiki></nowiki> tags around the URL. This will keep it from becoming a link.
  3. Add notation that the site is no longer active, including the last access date.


  • 14: http://www.badabwar.com (site is no longer active, accessed 2006.07.12)


*{{Endn|14}}: <nowiki>http://www.badabwar.com</nowiki> ''(site is no longer active, accessed 2006.07.12)''

Citing multiple references from the same source

If the article you are editing requires sourcing from more than one page of the material (e.g. different pages of the same Codex), then the main source must be listed under the main footnote number (e.g. 16), and the individual pages or chapters listed under the same number with consecutive letters added (e.g. 16a, 16b, 16c...).


Statement sourced from one section of source material [16a] ... end of paragraph with citation for a different section of the same source material.[16b]

The footnotes for these citations are are placed below the main source as an indented column by adding two asterisks (**) at the start of each footnote line. The source material is listed at the top, with a single asterisk (*).


Please practice testing this function in the Immaterium.

Tagging missing citations

If you stumble upon an article or a sentence that needs a verifiable source, you should use one of the following templates. Place the template at the bottom of the page, directly above the citations section.


For articles that do not have sources at all, or have very few.

{{Add'l cite}}

For articles that already have some sources, but need further work.

{{Cite section}}

For article sections that are not explicitly linked to a source, and whose canonicity is disputed.

{{Cite This}}

For sentences that are not explicitly linked to a source, and whose canonicity is disputed. This template is also used on footnotes that lack page numbers (or novel chapters).

Old styles of citation

Older forms of citation included the manual use of superscript (<sup> </sup>) and comment tags; whenever an Adept comes across this blasphemous formatting, they are urged to purge it with righteous fire, replacing it with the current citation method.


  • 0: This footnote hasn't been researched at all. Click the footnote number to see the in-line citation (it works both ways!).
