There are a growing number of Wikipedia projects, some very active, and others quite moribund. I propose that we invigorate them, and ensure that they each contain a minimum of information that will be of use to users. This way, people will be encouraged to use these projects and help in their growth.

I therefore suggest that we make a list of 1,000 basic articles that we should try to encourage to appear on every existing Wikipedia.

It still remains to define how detailed these 'articles' should be; or better yet, the list should include both significant articles (primary elements) and secondary topics/articles, which should either get short paragraph-length stubs, or be covered by a longer article.

These articles should be very basic, and incorporate the most essential information. In some cases, it will be only a table, while in other cases, it will be a stub. This will, however, provide some impetus for the smaller projects to grow. This project hopes to create easily translatable versions of these articles, containing core information at simple:Wikipedia:List of articles all languages should have.

If you support this effort, please add to the list.

How to use this list

There are several different ways to use this list. The first is to translate it into the language of your Wikipedia and see whether you have articles on all of these topics. The topics will eventually all be linked to articles in the Simple English Wikipedia. If you are missing an article, or if you are starting out with a new language, you may want to translate these basic articles. You can also check the language links in the Simple English articles for more comprehensive coverage of the topics in many other languages.
