Category:Pages with DOIs inactive as of 2019 August

This is a maintenance category. It is used for maintenance of the Wikipedia project and is not part of the encyclopedia. It contains pages that are not articles, or it groups articles by status rather than subject. Do not include this category in content categories. This is a hidden category. It is not shown on its member pages, unless the corresponding user preference 'Show hidden categories' is set. This is a tracking category. It builds and maintains a list of pages primarily for the sake of the list itself. Pages are added to tracking categories through templates.

This category is not shown on its member pages unless the appropriate user preference (appearance → show hidden categories) is set.

This category lists pages which transclude {{cite journal}}, where a digital object identifier doi value has been specified but then recognised as inactive.

This may represent:

• An incorrectly specified DOI. In this case, the DOI in question should be corrected.
• A DOI awaiting entry into the CrossRef 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.
• Publisher issues. A new publisher may have taken over a journal, or a publisher may not yet support DOIs. In this case, the DOI may not produce a hyperlink but still serves as a permanent identifier for the article in question. It should be marked using the |doi-broken-date= parameter of {{cite xxx}}. The article will then be correctly listed in this category until the DOI becomes active.
• 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.
