For example, the citation may never have had a <code class="tpl-para" style="word-break:break-word;">|url=</code>, or <code class="tpl-para" style="word-break:break-word;">|url=</code> may have been removed because it links to a site that violates the creator's copyright (see <a href="/w/index.php?title=%E0%AE%B5%E0%AE%BF%E0%AE%95%E0%AF%8D%E0%AE%95%E0%AE%BF%E0%AE%AA%E0%AF%8D%E0%AE%AA%E0%AF%80%E0%AE%9F%E0%AE%BF%E0%AE%AF%E0%AE%BE:COPYLINK&action=edit&redlink=1" class="new" title="விக்கிப்பீடியா:COPYLINK (கட்டுரை எழுதப்படவில்லை)">WP:COPYLINK</a>), or because <code class="tpl-para" style="word-break:break-word;">|url=</code> was deemed to be dead and (mistakenly) removed. If the citation never had <code class="tpl-para" style="word-break:break-word;">|url=</code> or it was removed for copyright violations, remove <code class="tpl-para" style="word-break:break-word;">|access-date=</code>.

The check digit is there to check whether the main part of the number is correct. If the ISBN is failing to validate, it is likely that there is a typo in the main part of the number.

It is not uncommon for the ISBN to be misprinted in the front matter but correct on the cover.</li> <li><b>Do</b> preview your edit and check that the new ISBN does now link to the correct source.</li></ul> <p>In very rare cases, publishers have released books with malformed ISBNs. If you are certain that a non-conforming ISBN truly corresponds to the published work, then you can add <code class="tpl-para" style="word-break:break-word;">|ignore-isbn-error=true</code> to the citation in order to suppress the error message. In many cases, books may have been reissued with a corrected ISBN.

As a general rule, avoid using templates in title-holding parameters unless you know that the template's effects are entirely visual (<code>{{<a href="/wiki/%E0%AE%B5%E0%AE%BE%E0%AE%B0%E0%AF%8D%E0%AE%AA%E0%AF%8D%E0%AE%AA%E0%AF%81%E0%AE%B0%E0%AF%81:!" title="வார்ப்புரு:!">!</a>}}</code> and the like). </p><p>This type of error may also occur in identifier-based templates (<code>{{<a href="/wiki/%E0%AE%B5%E0%AE%BE%E0%AE%B0%E0%AF%8D%E0%AE%AA%E0%AF%8D%E0%AE%AA%E0%AF%81%E0%AE%B0%E0%AF%81:Cite_doi" title="வார்ப்புரு:Cite doi">cite doi</a>}}</code>, etc.). When this happens, the error message is shown in the article but the error is actually located in the identifier-based citation template. </p><p>To resolve this error, remove wikilinks from title-holding parameters that are intended to be externally linked or remove the external URL, which will allow the internal wikilinks to work as expected. If wikilink-producing templates are important to the citation, move them out of the CS1 template but leave them inside the citation's <code class="nowrap" style=""><ref>...</ref></code> tags. Some of the functionality provided by templates may also be available through CS1 parameters. </p><p>To resolve errors in identifier-based citation templates, the template must be edited to correct the error.

To suppress the error after determining that the two-character initial is correct and not a typo, treat the name as if it were a corporate name by wrapping it in doubled parentheses: <code class="tpl-para" style="word-break:break-word;">|vauthors=..., Tatarinov IuS, ...</code> → <code class="tpl-para" style="word-break:break-word;">|vauthors=..., ((Tatarinov IuS)), ...</code> </p><p>Similarly, Chinese hyphenated given names may appear in PubMed listings. For example: 'Wang Hsien-yu' may be listed on PubMed as 'Wang Hy' which will result in a Vancouver error. When this occurs, and upon verification that such names are correct, wrap them in doubled parentheses. </p><p>Specific Rules for Names:<sup id="cite_ref-16" class="reference"><a href="#cite_note-16"><span class="cite-bracket">[</span>15<span class="cite-bracket">]</span></a></sup> </p> <ul><li><a rel="nofollow" class="external text" href="https://www.ncbi.nlm.nih.gov/books/NBK7282/box/A33071/?report=objectonly">Surnames with hyphens and other punctuation in them</a></li> <li><a rel="nofollow" class="external text" href="https://www.ncbi.nlm.nih.gov/books/NBK7282/box/A33081/?report=objectonly">Other surname rules</a></li> <li><a rel="nofollow" class="external text" href="https://www.ncbi.nlm.nih.gov/books/NBK7282/box/A33104/?report=objectonly">Given names containing punctuation, a prefix, a preposition, or particle</a></li> <li><a rel="nofollow" class="external text" href="https://www.ncbi.nlm.nih.gov/books/NBK7282/box/A33118/?report=objectonly">Degrees, titles, and honors before or after a personal name</a></li> <li><a rel="nofollow" class="external text" href="https://www.ncbi.nlm.nih.gov/books/NBK7282/box/A33127/?report=objectonly">Designations of rank within a family, such as Jr and III</a></li> <li><a rel="nofollow" class="external text" href="https://www.ncbi.nlm.nih.gov/books/NBK7282/box/A33134/?report=objectonly">Names appearing in non-roman alphabets (Cyrillic, Greek, Arabic, Hebrew, Korean) or character-based languages (Chinese, Japanese)</a></li> <li><a rel="nofollow" class="external text" href="https://www.ncbi.nlm.nih.gov/books/NBK7282/box/A33152/?report=objectonly">Organizations as author</a> <ul><li>cs1|2 does not obey the semicolon-as-separator rule.
