It is automatically generated from category tags at the bottoms of articles and most other pages. Nearly all of the articles available so far on the website can be found through these subject indexes. If you are simply looking to browse articles by topic, there are three top-level pages to choose from: Category:Main topic classifications—probably what you are looking for: Arts, History, Technology, etc. Category:Fundamental categories—organizes articles into 'abstract' ontological categories in a way that every article can reasonably be expected to be classified within it; and Portal:Contents/Categories—a hand-crafted list of first- and second-level topic categories. For biographies, see Category:People categories by parameter. Category:Contents is technically at the top of the category hierarchy, but contains many categories useful to editors but not readers. Special:Categories lists every category alphabetically. Alphabetical lists of articles Wikipedia's alphabetical article indexes Special:Allpages lists all of the current pages in Wikipedia. Portal:Contents/A–Z index provides an easy way to skip to a particular part of the alphabet in the list of all articles.
