แม่แบบ:Citation Style documentation/registration

Citations of online sources that require registration or a subscription are acceptable in Wikipedia as documented in Verifiability § Access to sources. As a courtesy to readers and other editors, editors should 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 verifying claims in articles.

Four access levels can be used:

• access indicator for named identifiers:
  • Freely accessible free: the source is free to read for anyone
• access indicators for url-holding parameters:
  • Free registration required registration: a free registration is required to access the source
  • Free access subject to limited trial, subscription normally required limited: there are other constraints (such as a cap on daily views) to freely access this source
  • Paid subscription required subscription: the source is only accessible via a paid subscription ("paywall")

As there are often multiple external links with different access levels in the same citation, each value is attributed to a specific external link.

Access indicators for url-holding parameters

Online sources linked by แม่แบบ:Para, แม่แบบ:Para, แม่แบบ:Para, แม่แบบ:Para, แม่แบบ:Para, แม่แบบ:Para, and แม่แบบ:Para 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 may not be marked as free.

URL-holding and access-indicator parameters

URL	Access	Allowed keywords
แม่แบบ:Para	แม่แบบ:Para	registration Free registration required limited Free access subject to limited trial, subscription normally required subscription Paid subscription required
แม่แบบ:Para	แม่แบบ:Para
แม่แบบ:Para	แม่แบบ:Para
แม่แบบ:Para	แม่แบบ:Para
แม่แบบ:Para	แม่แบบ:Para
แม่แบบ:Para	แม่แบบ:Para
แม่แบบ:Para	แม่แบบ:Para

For example, this cites a web page that requires registration but not subscription:

{{cite web |url=https://example.com/nifty_data.php |url-access=registration |date=2021-04-15 |title=Nifty example data}}

which renders as:

Access indicator for named identifiers

Links inserted by named identifiers are presumed to lie behind a paywall or registration barrier – exceptions listed below. When they are 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. When the sources linked by these named-identifier parameters are not presumed to carry a free-to-read full text (for instance because they're just abstracting services), they may not be marked as limited, registration, or subscription.

Named-identifier and access-indicator parameters

Identifier	Access	Allowed keywords
แม่แบบ:Para	แม่แบบ:Para	free Freely accessible
แม่แบบ:Para	แม่แบบ:Para
แม่แบบ:Para	แม่แบบ:Para
แม่แบบ:Para	แม่แบบ:Para
แม่แบบ:Para	แม่แบบ:Para
แม่แบบ:Para	แม่แบบ:Para
แม่แบบ:Para	แม่แบบ:Para

Some named-identifiers are always free-to-read. For those named identifiers there are no access-indicator parameters; the access level is automatically indicated by the template. These named identifiers are:

• แม่แบบ:Para
• แม่แบบ:Para
• แม่แบบ:Para
• แม่แบบ:Para
• แม่แบบ:Para
• แม่แบบ:Para
