Category:Pages with DOI errors

This is a maintenance category, used for maintenance of the Wikipedia project. It is not part of the encyclopedia and contains non-article pages, or groups articles by status rather than subject. Do not include this category in content categories.

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

Administrators: Please do not delete this category as empty! This category may be empty occasionally or even most of the time.

If this category has 25 items or more, it will be reported as a backlog. (recount)

This category contains pages that contains invalid digital object identifiers (DOIs). It is populated by {{doi}}. To clean up, ensure that the DOI is specified as:

• {{doi|10.Foobar/1234}} and not {{doi|doi:10.Foobar/1234}}
• {{doi|10.Foobar/1234}} and not {{doi|http://dx.doi.org/10.Foobar/1234}}

or similar. DOI values are marked as invalid if they do not begin with 10.
