Wikipedia:Citing sources/Further considerations

This page includes some additional considerations for citing sources. The information is here so as not to distract from content on the main Citing sources project page, which is designed to help newer editors get started quickly. This page provides additional information for interested editors.

Pre-emptive archiving

See also: Wikipedia:List of web archives on Wikipedia

The content of any webpage may change at any moment, or disappear completely. To ensure link accessibility and stability, please consider pre-emptively adding an archive URL from an archive source such as the Internet Archive or WebCite. Wikipedia citation templates all allow for archive information to be included along with the original reference.

Internet Archive

See also: Help:Using the Wayback Machine

The Internet Archive, also known as the Wayback Machine, allows on-demand archiving as well as periodically crawling web pages on its own schedule. Where possible and subject to copyright protection, it makes an archive copy of each page.

Enter the original URL of the web page of interest into the form at web.archive.org and then click BROWSE HISTORY to see if a particular URL has already been archived. Alternatively, prepend https://web.archive.org/web/*/ to the URL of interest.

The next screen may show a calendar indicating the snapshot dates for all archived copies of that page. Click a date to see that archived copy. For some requested pages, the Wayback Machine will return an error message explaining why that particular page has not and cannot be archived.

If the page has not yet been archived, there may be a box near the bottom of the page with a link inviting the user to Save this url in the Wayback Machine (this may also occur if the page has been very recently archived for the first time, as archived pages often do not instantly become available).

• If the user does not have a Wayback Machine account or is logged out, clicking this link will show the current version of the requested web page and start the process that will attempt to archive the page.
• If the user has a Wayback Machine account and is logged in, clicking this link will instead bring up the form at web.archive.org/save, with the URL of interest preloaded; this provides additional functionality, such as the option to save not only the page itself but also all pages linked from it, and the option to additionally save a screenshot of the current state of the web page in question. Once the desired options have been selected, click SAVE PAGE to start the archiving process.

If the archiving process is successful, the archived copy will become available shortly after the process is completed (there may sometimes be a delay of up to a few hours before the archived copy can be accessed).

If the page has already been archived in the Wayback Machine, but you wish to save a new version (because the page changed since being last archived), you can archive it again by typing in the URL https://web.archive.org/save/https://www.url.com in your browser (where www.url.com should be replaced with the URL of the document you wish to save). Alternatively, enter the URL of interest into the form at web.archive.org/save and then click SAVE PAGE.

Using the shortened footnote template

Template {{Sfn}} links to {{Citation}} automatically, and links to {{cite book}}, {{cite web}}, {{cite news}}, {{cite journal}}, if |ref= is set to "harv". {{Sfn}} also combines identical footnotes automatically, so footnote names are not necessary. It links on the |year= and |last= parameters. The method was introduced much more recently than {{harvnb}}.

Using the shortened footnote template when the author is not known

Template {{Sfn}} links on the |year= and |last= parameters of the {{cite xxx}} and {{citation}} templates. This can be changed if the authors name is not known by setting a new ref parameter using the {{sfnref}} template: |ref={{sfnref|xxx|yyy}}

Using freehand anchors

Most citation templates (for example {{citation}}, {{cite journal}}, {{cite book}}, {{cite web}}, {{cite news}}, etc.) can create wikilinks by using the ref parameter to create hyperlink destination anchors, thus allowing the short note citation to link to them using # (in the same way as would a link to a same-page section heading). For references written freehand, anchors can be created with the inclusion of some identifying tags.

The Sun is pretty big,<ref>[[#refMiller2005|Miller (2005)]], p.23.</ref>
but the Moon is not so big.<ref>[[#refBrown2006|Brown (2006)]], p.46.</ref>

Using Wikicite

The template {{Wikicite}} method is used in about 1000 articles (as of 1 August 2015).

The Sun is pretty big,<ref>[[#refMiller2005|Miller (2005)]], p.23.</ref>

There exists a tool Yadcard- ISBN reference generating tool that will provide sfn (Shortened foot note)s and (Named reference)s from URL / DOI / ISBN. It is a bookmarklet- ie, it is recorded on a browser as a bookmark, Ctrl-D and can be placed on browser's bookmark toolbar.
