[[:|WP:CATS]]

A category scheme is a way to index Wikipedia articles. Many category schemes are possible, and there is no scheme that is clearly the best. Furthermore, many of these categories are incomplete — some categorise only the broadest topics, others don't even get that far. See the discussion page for other proposed category schemes. The topmost levels are included below. Click on entries to see successively lower levels in each scheme.

Lists of articles

Wikipedia:Concise -- a list of articles comprising the "Wikipedia Concise", the Wikipedia version of a concise encyclopedia. Under construction. Slated for 15,000 topics, but currently lists about 1000. Haphazardly constructed via random edits.
Wikipedia:Basic topics -- phased out. Replaced by the List of basic topic lists.
List of basic topic lists -- includes short lists of key topics on major subjects.
List of topic lists -- intended to be a comprehensive list of article lists, arranged by subject. Under construction.
Wikipedia:Browse by overview - List of major articles, called "overview articles". Articles with the same names as portals and major categories.

Lists of categories

Wikipedia:Browse - Lists the top two levels of the category system; cool format.
Category:Categories - Lists top-level categories
- Category:Fundamental - the first level of categories

Pros: centralized Cons: cumbersome (can't be edited directly), awkward (category list not present at the point of data-entry), easier to navigate down the tree than up it, administrative category system hard to find (especially for newbies)

See also: Wikipedia:categorization for information and policies about creating and applying categories and categories outside article space.

Lists of portals

Portals are theme pages. Most feature articles, a picture or two, and news items. Many also contain topic lists, and some contain lists of categories.

Portal:Browse - The portal of portals. Lists all completed portals.
