Template:ISSN/doc

Usage
This template generates a link for finding data about a (print or on-line) publication via its International Standard Serial Number (ISSN). The ISSN refers to the particular publication, not to a specific issue (or date) of that publication. The ISSN is used to help establish the publication as a Wikipedia reliable source.

For a publication with the ISSN 1234-5678, use 1234-5678. The template supports up to 9 ISSNs.

Examples

It the leading "ISSN" link should not occur (for example in longer lists), it can be suppressed using the yes parameter:

Find ISSN of publication

 * Find the ISSN by searching with the publication's name on the Colorado Alliance of Research Libraries web site.

Note:

An ISSN is always eight digits long. Scroll down the Worldcat page to find the ISSN. Do not rely on the digits shown in the Worldcat URL for the particular publication, since the URL sometimes shows only seven digits, which is invalid to use as the ISSN.

Error checking
This template uses Module:Check isxn to validate the ISSN. If the ISSN is not valid, this subtemplate will still generate the link, and it will add the article to Category:Pages with ISSN errors. To be valid, the ISSN must contain a hyphen separating the two groups of four digits.


 * (valid ISSN, but no hyphen)  produces
 * (valid ISSN, with hyphen)  produces

Since invalid ISSNs are sometimes used in publications, it is possible to disable the validity check for individual ISSNs given as parameters. In order to do so, add invalid?=yes (with ? replaced by the parameter number 1 to 9) to the template. In this case, the article will be added to Category:Articles with invalid ISSNs.
