Template:Broken doi explanation

This category lists pages that have cs1|2 templates that use doi, where a digital object identifier doi value has been specified but then recognized as inactive. These are collected in.

This may represent:
 * An incorrectly specified DOI. In this case, the DOI in question should be corrected.
 * A DOI awaiting entry into the Handle System system. In this case, the DOI will soon be active, and a bot will remove the doi-broken-date parameter next time it checks the transcluding article.  The article will be correctly listed in this category but does not require further editing until the DOI becomes active.
 * A system error with the DOI resolving agency. This should be reported to the DOI resolver (e.g. Crossref) so that it can be fixed - preferably including a link to the journal article claiming the link as further information.
 * Publisher issues. A new publisher may have taken over a journal, or a publisher may not yet support DOIs, despite assigning them.  In this case, the DOI may not produce a usable hyperlink but still serves as a permanent identifier for the article in question.  It should be marked using the doi-broken-date parameter of .  The article will then be correctly listed in this category until the DOI becomes active.  The DOI error report method might not work for these, since the publisher and the DOI owner are not the same.
 * The DOI has changed, such as the Archives of Pathology & Laboratory Medicine which changed its DOIs when it changed publishers.
 * Internal use only DOI. The American Medical Association, for example, assigns a DOI to all of its journal articles, but many of these are only in the META tags on the web pages and Crossref will not resolve these.  Since these can be found with an Internet search engine and might eventually resolve they should be left in the citation.
 * The DOI resolves to a dead link. These are hard to report, since the doi.org thinks the DOI works and sometimes the journal no longer exists.
