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 hidden category. It is not shown on its member pages, unless the corresponding user preference (Appearance → Show hidden categories) is set.

This category is called by entering "ne2007" or "ne2010" in the ref field of the language info box.

A few articles have the category added manually, so they will also be updated if we go to a new edition of Nationalencyklopedin.

See List of languages by number of native speakers#Nationalencyklopedin.
