The subcategories of this category are hidden categories. To add a category to this category, add ((Hidden category)) , ((Maintenance category|hidden=yes)) , or __HIDDENCAT__. A subcategory of a hidden category may or may not itself be hidden, depending on a template or a magic word in the subcategory or in a parent category.
- 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).

Description: This category contains
hidden categories. Unlike normal categories, these are not displayed at the bottom of pages that are included in them, and are therefore hidden from readers.
Typically, categories should be hidden if they are concerned with the maintenance or administration of the Wikipedia project itself but include mainspace articles.
Previewing a page whilst editing it will list the hidden categories used at the bottom of the page. If you have
created a user account, you can make hidden categories show up next to normal categories at the bottom of all pages by setting the
user preference 'Show hidden categories'.
