Please do not use raNdOM capitalization.</li> <li>Names <strong>must not</strong> be purely numeric; the software will accept something like <code>":31337"</code> (which is punctuation plus a number), but it will ignore <code>"31337"</code> (purely numeric).</li> <li>Names should have semantic value, so that they can be more easily distinguished from each other by human editors who are looking at the wikitext. This means that ref names like <code>"Nguyen 2010"</code> are preferred to names like <code>":31337"</code>.</li> <li>Names must be unique. You may not use the same name to define different groups or footnotes. Try to avoid picking a name that someone else is likely to choose for a new citation, such as <code>":0"</code> or <code>"NYT"</code>.</li> <li>Please consider keeping reference names short, simple, and restricted to the standard <a href="/wiki/English_alphabet" title="English alphabet">English alphabet</a> and numerals. If spaces are used, the following technical restrictions become relevant: <ul><li>Quotation marks are preferred but optional if the only characters used are letters <code>A–Z</code>, <code>a–z</code>, digits <code>0–9</code>, and the symbols <code style="word-break: break-all;">!$%&()*,-.:;<@[]^_`{|}~</code>. That is, all printable ASCII characters except <code style="word-break: break-all;">#"'/=<>?\</code> and space.</li> <li>Inclusion of any other characters, <em>including spaces</em>, requires that the reference name be enclosed in quotes; for example, <code>name="John Smith"</code>. But quote-enclosed reference names may not include a less-than sign (<code><</code>) or a double straight quote symbol (<code>"</code>), which may however be included by <a href="/wiki/Escape_sequence" title="Escape sequence">escaping</a> as <code>&lt;</code> and <code>&quot;</code> respectively.</li> <li>The quote marks must be the standard, straight, double quotation marks (<code>"</code>); curly or other quotes will be parsed as part of the reference name.</li></ul></li> <li>You may optionally provide reference names even when the reference name is not required.

This is primarily a change in the source code and does not affect the display of the article to a reader. The primary effects are for editors, as described below. </p><p>The LDR method removes any citation details or notes that could disrupt the edit window while editing the body of the text, which is especially useful if they are vertical or otherwise span multiple lines. Additionally, this centralised reference list section can be opened by itself if any of the citation entries need modification, which can be especially helpful if attempting to modify a reference that is used multiple times—avoiding any need to search the entire source for it. </p><p>A drawback of the approach is that these references can be harder to insert into the source, because they are separated from the text. The editor must either open the entire document to see the source for both the text and the reference list, or alternatively use a two-step procedure, first entering the identifier <code class="nowrap" style=""><ref name="<var>name</var>" /></code> in the main text and then opening the reference listing section to enter the source or footnote as <code class="nowrap" style=""><ref name="<var>name</var>"><var>content</var></ref></code>. Another overhead of this approach is that the list at the end of the article must be organised so that they can be found easily by an editor—most likely arranged alphabetically in the edit window by refname as this is most likely to retain source integrity and usefulness, even if the sections of the text are changed. </p><p>While it is often tidier to remove all citations from the source text, an acceptable compromise (especially for small articles) could be to only use LDR for citations used multiple times. This is because they already use the refname code so that they can be in multiple places—a simple move of the reference's source code from its first appearance to the reflist is a minor change. Additionally, these citations are more likely to need reviewing or modification, because they are more important to the article and contain more details, and making them easier to find and modify can be very helpful. Finally, this also maintains source integrity if the first instance of the reference changes, as noted above. </p><p>Additionally, a user-made script <a href="/wiki/User:PleaseStand/References_segregator" title="User:PleaseStand/References segregator">User:PleaseStand/References segregator</a> allows you to automatically separate citations from the edit window, and temporarily collect them in a separated "inline citation" window. In this format the citations can be manually inserted into the reference list. This can have some of the benefits of permanent LDRs where their use is not practical or is against consensus. However, please note that before saving the page, any contents of this window will be replaced into the main text source at the first matching <code class="nowrap" style=""><ref name="<var>name</var>" /></code> tag unless it is manually emptied. As outlined on its page and below, it has an automatic conversion script that can process existing citations into a reference list by itself, but it is uncertain whether it can do this migration while editing. </p><p>Finally, there are some misconceptions about list-defined footnotes: </p> <ol><li>One of these is that the creation of separated footnote lists requires the use of list-defined footnotes. However, using a <a href="/wiki/Wikipedia:REFLIST#Grouped_references" class="mw-redirect" title="Wikipedia:REFLIST">'group' name</a> to differentiate various kinds of footnotes, is available regardless of whether list-defined or in-line footnotes are used. For example, in both cases one can designate notes as a group called "Note", and separate them from simple citations by using the in-line label <code class="nowrap" style=""><ref group="Note" name="<var>name</var>" /></code> (The complete explanation of the use of group names is illustrated in the second example in the <a href="#Examples">section immediately above</a>.)</li> <li>Another misconception is that there is an "either-or" choice between use of list-defined footnotes and in-line footnotes, and that all citations in an article must follow only one of the styles. In fact, <code>{{<a href="/wiki/Template:Reflist" title="Template:Reflist">reflist</a>|refs= }}</code> is entirely compatible with the use of in-line footnotes in the form <code class="nowrap" style=""><ref><var>content</var></ref></code> or <code class="nowrap" style=""><ref name="<var>name</var>"><var>content</var></ref></code>. Although use of both systems in the same article might appear confusing or undesirable, it is a fact that the two systems can be mixed indiscriminately with the template <code>{{<a href="/wiki/Template:Reflist" title="Template:Reflist">reflist</a>|refs= }}</code>.</li></ol> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="Errors" data-mw-thread-id="h-Errors"><span data-mw-comment-start="" id="h-Errors"></span>Errors<span data-mw-comment-end="h-Errors"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Help:List-defined_references&action=edit&section=5" title="Edit section: Errors"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span><!--__DTELLIPSISBUTTON__{"threadItem":{"headingLevel":2,"name":"h-","type":"heading","level":0,"id":"h-Errors","replies":[]}}--></div> <p>Sometimes referencing can produce errors that show up in red text.
