(Restore and clarify; "free-to-read" is not a well-recognised term, plus it's ambiguous (free as in beer or free as in freedom). Sometimes we say "freely accessible" but that's also slightly ambiguous. We can see "gratis copy" but that would include copies which require gratis registration.)

Revision as of 15:46, 17 April 2020

These identifiers create links and are designed to accept a single value. Using multiple values or other text will break the link and/or invalidate the identifier. In general, the parameters should include only the variable part of the identifier, e.g. |rfc=822 or |pmc=345678.

When an URL is equivalent to the link produced by the corresponding identifier (such as a DOI), don't add it to any URL parameter but use the appropriate identifier parameter, which is more stable and may allow to specify the access status. The |url= parameter or title link can then be used for its prime purpose of providing a convenience link to an open access copy (as in, at least accessible to everyone for free) which would not otherwise be obviously accessible.
