href="/wiki/Biological_databases" class="mw-redirect" title="Biological databases">biological</a> and <a href="/wiki/Taxonomic_databases" class="mw-redirect" title="Taxonomic databases">taxonomic databases</a> for purposes of establishing a point of reference for each catalogued taxon. Assigning a taxon with a permanent identifier such as a string of numbers allows for information such as <a href="/wiki/Taxonomic_classification" class="mw-redirect" title="Taxonomic classification">taxonomic classification</a> to be updated without affecting the ability to retrieve or reference the data of the respective taxon. A taxon identifier works in much the same way that a <a href="/wiki/Barcode" title="Barcode">barcode</a> is used to retrieve data about an item of interest. When used on Wikipedia, taxon identifiers can be found near the bottom of Wikipedia pages, linking to records on <a href="/wiki/Taxonomic_database" title="Taxonomic database">taxonomic databases</a>. In many cases, each taxon name in a taxonomic database has a unique identifier, although this is not always the case. (For example, the <a href="/wiki/International_Plant_Names_Index" title="International Plant Names Index">International Plant Names Index</a> regularly has multiple identifiers for a taxon name, often but not always of the form <i>N</i>-1, <i>N</i>-2, etc.) </p><p>Taxon identifiers enable researchers to search more easily for pertinent information on the subject of an article, without needing to disambiguate the subject manually. For example, taxon identifiers are used in species articles so that the information in the article can be easily cross-referenced with the popular <a href="/wiki/Catalogue_of_Life" title="Catalogue of Life">Catalogue of Life</a> database. </p><p>More generally, taxon identifiers are a method of creating and maintaining index terms for bibliographical material. The links produced by the <span class="nowrap">{{</span><a href="/wiki/Template:Taxonbar" title="Template:Taxonbar">Taxonbar</a><span class="nowrap">}}</span> template on Wikipedia go to taxon information pages of online biological or taxonomic databases. As an example, the Wikipedia Taxonbar information for <i><a href="/wiki/Sequoiadendron_giganteum" title="Sequoiadendron giganteum">Sequoiadendron giganteum</a></i> looks like this: </p> <table>
