The Core Topics subproject of the Version 1.0 Editorial Team is intended to identify and work toward improvement of the most important articles (realizing that "importance" is subjective). Currently our work is limited to about 150 articles, which are listed with comments below. A [[Wikipedia:Version 1.0 Editorial Team/Core topics/Supplement|supplementary list]], similar in size, has been created to cover some other important subjects.

==How you can help==
If you're interested in helping, here are some good places to start:

;Individually
*Work on any article listed in the tree and update its status if needed. Especially, use the article status summary as a guide. The "Start Class" topics are more than stubs but often need substantial work.

;Collaborations
*Core topics and stubs at [[WP:Article Collaboration and Improvement Drive]].

== Background ==
This was begun in December 2004, by popular demand, more or less, to be a list of about 150 core subjects that would go in a "release" version of Wikipedia.

The list is small so as to be tightly focused.  Articles on individual countries are core topics, but beyond the scope of this list because there are so many and their value is clear.  Biographies are beyond the scope of this list because their value when considered individually is too subjective.  Other contenders for core articles include articles on the English language, timelines, maps and any reference material.

==Article status summary==
===Elite Nine===
{| class="wikitable"
! Article !! Quality !! Comments
|-
| [[Natural science]]{{Class|C}} || reasonable scope, with ~75 citations
|-
| [[Personal life]]{{Class|C}} || reasonable scope, with ~30 citations
|-
| [[Social science]]{{Class|C}} || ok scope, scatty and oddly balanced, ~40 citations
|-
| [[Geography]]{{Class|C}} || good scope, if a bit scatty, ~30 citations
|-

*[[Portal:Contents]] - list of subject lists. Each of the following pages is a list of subjects, but their links lead to navigation pages rather than to articles.  Great for identifying core topics.
** [[Portal:Contents/Indexes]] - almost all the index page titles are major subjects.  The indexes themselves attempt to be comprehensive and mix major and minor topics together alphabetically with no distinction between them.
** [[Portal:Contents/Outlines]] - in addition to their titles representing major subjects, each outline is further broken down into major subjects within its subject.  For example, geography is broken down into human geography, physical geography, landforms, regions, etc.  You can tell how major a topic is by where it is on the knowledge tree. If you are hunting for core topics, this system will help you find many.
