WK 13.2 Categorization

The central goal of the category system is to provide navigational links to Wikipedia pages in a hierarchy of categories which readers, knowing essential, defining, characteristics of a topic, can browse and quickly find sets of pages on topics that are defined by those characteristics. Moreover, categories are not the only means of enabling users to browse sets of related pages. Other tools which may be used instead of or alongside categories in particular instances include lists and navigation boxes. When naming a category, one should be particularly careful and choose its name accurately. After you have determined an appropriate category name and know its parent category, you are ready to create the new category. To create a category, first add an article to that category. In such cases, the desired contents of the category should be described on the category page, similar to how the list selection criteria are described in a stand-alone list. Furthermore, the description can also contain links to other Wikipedia pages, in particular to other related categories which do not appear directly as subcategories or parent categories. 

What is new to me is that every Wikipedia page should belong to at least one category. In addition, each categorized page should be placed in all of the most specific categories to which it logically belongs. While it should typically be clear from the name of an existing category which pages it should contain, the text of the category page may sometimes provide additional information on potential category contents. 

Categorization of articles must be verifiable. It should be clear from verifiable information in the article why it was placed in each of its categories.
