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 is a tracking category. It builds and maintains a list of pages primarily for the sake of the list itself. They are not part of the encyclopedia's categorization scheme. This category is hidden on its member pages—unless the corresponding user preference (Appearance → Show hidden categories) is set. These categories can be used to track, build and organize lists of pages needing "attention en masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience. These categories also serve to aggregate members of several lists or sub-categories into a larger, more efficient list (discriminated by classifications).

This category contains pages transcluding Template:Infobox animanga (talk) with unknown parameters (undefined, misspelled, etc.).

Pages are typically sorted alphabetically by the unknown parameter that is used, e.g. pages using unknown parameter |foo= will be sorted under "F". The name of the page is typically used as a secondary sort key.

Unknown parameters can be detected using Module:Check for unknown parameters in the template. To show the information listed here on a category page, use ((Unknown parameters category)) on the category page.

This category lists articles with obsolete or deprecated parameters from ((Infobox animanga)) along with various other issues.

Currently, this category contains articles with the following issues:

• Unknown parameters
• |volumes= is set to 1 or less, and |last= and |magazine= are unset
  • Typically, these can be fixed by replacing all three parameters with |published=.
• |genre= contains a demographic group or "ecchi"
  • Remove demographic group and "ecchi" from parameter. If there is a ((Infobox animanga/Print)) component, check that the appropriate demographic group is listed there.
• |publisher=, |publisher_en=, |magazine=, |magazine_en=, |studio=, |network= or |network_en= contains a flag icon.
  • Remove the flag icon or, if non-Japanese information, integrate into the article if sources can be found.
• |network_en= contains the following video on demand websites: AnimeLab, Crunchyroll, Daisuki, Hulu, Viewster, YouTube.
