Template:Citation Style documentation/registration: Difference between revisions

<span id="csdoc_access_level"></span>

Citations of online sources that require registration or a subscription are acceptable in Wikipedia as documented in [[WP:PAYWALL|Verifiability § Access to sources]]<!-- {{Section link|Wikipedia:Verifiability|Access to sources}} -->. As a courtesy to readers and other editors, editors should<!-- can --> signal restrictions on access to material provided via the external links included in a citation. These levels describe requirements or constraints related to accessing and viewing the cited material; they are not intended to indicate the ability to reuse, or the copyright status, of the material, since that status is not relevant to [[WP:V|verifying claims in articles]].  

=====Access indicators for url-holding parameters=====

{{see also|WP:CONLINK}}

Online sources linked by {{para|url}}, {{para|article-url}}, {{para|chapter-url}}, {{para|contribution-url}}, {{para|entry-url}}, {{para|map-url}}, and {{para|section-url}} are presumed to be free-to-read. When they are not free-to-read, editors should mark those sources with the matching access-indicator parameter so that an appropriate icon is included in the rendered citation. Because the sources linked by these URL-holding parameters are presumed to be free-to-read, they are not marked as <code>free</code>.  If the registration/limited/subscription access to the source goes dead and is no longer available, then remove the access-indicator parameter and add {{para|archive-url}} and {{para|archive-date}} values if possible.
