About this template

Template:Citation/identifier is a helper template to Wikipedia's citation system. This template ties in with other templates like Template:Citation/core. Specifically, it helps render how identifiers like ASIN, ISBN, and JSTOR are rendered in references, producing a consistent look throughout the encyclopedia.

Stand-alone templates

Most of the fields have stand-alone templates for other uses. ISBN, PMID and RFC are directly supported by the MediaWiki software.

Usage

Each identifier is invoked by use of |identifier= to define the type and one or more input parameters:
