Help:Editing/House Style/Sources

Hardcopy Sources

 * Template:BookReference: This is used to reference a specific book which will have been documented in the Books page. The idea of this is that if you have sourced the information for a page directly from a book, then it should be possible to provide the details of that book.

Example: which can be found on the page Characteristic times Ring Element is Ring Zero.
 * : $\S 4.17$: Theorem $28$


 * Template:Citation: This is used to reference a specific article in a journal. This is still under development, as the individual Journal entries still need to be worked on.

Examples of their use can be found on various Mathematicians pages, for example: which appears on the page for.

The style of this is still evolving.

Online Sources
There are templates for the following online sources. Each one has been crafted so as to produce a reference in the style requested by the online source in question.


 * Template:MathWorld: This provides a direct link to a page on the http://mathworld.wolfram.com/ website.

Example: which can be found in the page Area of Sector.


 * Template:Planetmath: This provides a direct link to a page on the http://planetmath.org/ website.

Example: which can be found in the page Urysohn's Lemma.


 * Template:MacTutor Biography: This provides a direct link to a page on the http://www-history.mcs.st-andrews.ac.uk/history/index.html website.

Example:

which can be found in the page for. Note that the link presentation is taken from the page the template is invoked from.


 * Template:Khanacademy: This provides a direct link to the Khan Academy.

Example: which can be found in the page Limit of Sine of X over X/Geometric Proof.


 * Template:Metamath: This provides a direct link to Metamath.

Example: which can be found in the page Principle of Transfinite Recursion.


 * Template:OEIS: This provides a direct link to the On-Line Encyclopedia of Integer Sequences.

Example: which can be found in the page Square Root of 2 is Irrational.


 * Template:TORI: This provides a direct link to the TORI source site.

Example: which can be found in the page Definition:Tetration.

Acceptability of Online Sources
NOTE: The above are the ONLY web resources which are to be used as general citation sources. Others may be added to the above as and when they come to our attention as being particularly useful. So feel free to challenge this assertion if you find something which appears to be a particularly rich and productive resource.

Scholarly papers which are available online may usually also be cited.

What are not generally acceptable include:
 * Lecture notes for university courses available online (because they do not stay online forever, and this causes dead links)
 * Links to pages in homework help forums
 * Discussion pages in any web forum
 * Wikipedia -- not because we don't like them, but because as they are self-proclaimed tertiary source, there is no need to do so -- we would rather go to the actual source works.
