साँचा: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 can signal the access restrictions of the external links included in a citation.

चार उपलब्धता स्तर काम में लिए जा सकते हैं:

• free: स्रोत कहीं से भी मुक्त रूप से पढ़ा जा सकता है (यह सामान्यतः मुक्त रूप से उपलब्ध लेखों पर लागू होता है)
• registration: स्रोत तक पहुँचने के लिए मुक्त पंजीकरण आवश्यक है
• limited: इसका स्रोत मुक्त रूप से प्राप्त करने के लिए कुछ अन्य बाध्यतायें हैं (जैसे दैनिक दृश्य संख्या परिमित हो)
• subscription: स्रोत को केवल सशुल्क सदस्यता ("पेवॉल") लेकर देखा जा सकता है

As there are often multiple external links with different access levels in the same citation, these values are attributed to a particular external link.

Access level of |url=

Links inserted with |url= are expected to be free to read by default. If not, editors can use one of

• |url-access=subscription
• |url-access=registration
• |url-access=limited

to indicate the relevant access restriction.

Access level of identifiers

Links inserted by identifiers such as |doi= are not expected to offer a free full text by default. If they do, editors can use |doi-access=free (in the case of |doi=) to indicate the relevant access level. The following identifiers are supported:

• |bibcode= with |bibcode-access=free
• |doi= with |doi-access=free
• |hdl= with |hdl-access=free
• |jstor= with |jstor-access=free
• |ol= with |ol-access=free
• |osti= with |osti-access=free

Some identifiers always link to free full texts. In this case, the access level is automatically indicated by the template. This is the case for |arxiv=, |biorxiv=, |citeseerx=, |pmc=, |rfc= and |ssrn=.

Ambiguous access parameters

The parameters |registration=yes and |subscription=yes can also be used to indicate the access level of a citation. However, they do not indicate which link they apply to, so editors are encouraged to use |url-access=registration and |url-access=subscription instead, when the restriction applies to |url=. If the restriction applies to an identifier, these parameters should be omitted.

These parameters add a link note to the end of the citation:

• registration: For online sources that require registration, set |registration=yes (or y, or true); superseded by subscription if both are set.
• subscription: For online sources that require a subscription, set |subscription=yes (or y, or true); supersedes registration if both are set.

Setting |registration= or |subscription= to any value other than y, yes, or true will generate an error message.
