===Diffusing large categories===

{{Shortcut|WP:DIFFUSE}}{{redirect|WP:DIFFUSE|conflicts|Wikipedia:Diffusing conflict}}

Although there is no limit on the size of categories, a large category will often be broken down ("diffused") into smaller, more specific subcategories. For example, [[:Category:Rivers of Europe]] contains no articles about specific rivers directly,; they are all in subcategories.

{{anchor|Metacategories|META}}A category may be diffused using several coexisting schemes; for example, [[:Category:Albums]] is broken down by artist, by date, by genre etc. '''Metacategories''' may be created as ways of organizing schemes of subcategories. For example, the subcategories called "''Artistname'' albums" are not placed directly into [[:Category:Albums]], but into the metacategory [[:Category:Albums by artist]], which itself appears in Category:Albums. (See [[:Category:Categories by parameter]])
