Explore the vast knowledge of [[Wikipedia]] through these helpful resources. If you have a specific topic in mind, use Wikipedia's search box. If you don't know exactly what you are looking for or wish to explore broad areas, click on a link in the header menu at the top of this page, or begin your browsing below:


== Navigating Wikipedia's subjects ==
There are two ways to look things up in Wikipedia: by searching or by browsing.
Wikipedia organizes its content into distinct subject classifications, each with further subdivisions.
* If you know the name of an article for which you are looking, simply type it into Wikipedia's [[Help:Searching|search]] box.
* If you would like to look around the encyclopedia to see what is on it, use Wikipedia's '''Contents''' pages. Lists and [[Index (publishing)|indices]] are examples of contents for a published work, and Wikipedia has [[#Wikipedia's indices|many of each]], including a [[Portal:Contents/Quick index|complete alphabetical index]] and [[#Categorical indices|indices by category]]. <br /> Links to all of Wikipedia's main contents pages are presented below, and they in turn link to the more specific pages.


=== Culture ===
== Curated article collections ==
Explore the diverse cultures, arts, beliefs, and customs of human societies.
*[[Wikipedia:Contents/Culture and the arts|Culture]]


=== Overview articles ===
=== Geography ===
Discover the wonders of Earth's lands, features, inhabitants, and planetary phenomena.
*[[Wikipedia:Contents/Geography and places|Geography]]


=== Health ===
Overview articles summarize in prose a broad topic like [[biology]], and also have illustrations and links to subtopics like [[cell biology]], biographies like [[Carl Linnaeus]], and other related articles like [[Human Genome Project]].

* [[Portal:Contents/Overviews]] lists overview articles from covered areas of knowledge in a single page.
*[[Wikipedia:Contents/Health and fitness|Health]]


=== Outline pages ===
=== History ===
Dive into the past through written records and scholarly exploration.
*[[Wikipedia:Contents/History and events|History]]


==== Timelines ====
Outline pages have [[tree structure|trees]] of topics in an [[Outline (list)|outline format]], which in turn are linked to further outlines and articles providing more detail. Outlines show how important subtopics relate to each other based on how they are arranged in the tree, and they are useful as a more condensed, non-prose alternative to overview articles.
Explore chronological events through our comprehensive timelines.
* [[Portal:Contents/Outlines]] is a comprehensive list of "Outline of __" pages, organized by subject. It is itself an outline, that links (almost) exclusively to other outlines.
*[[List of timelines]]
* [[Outline of academic disciplines]] covers subjects studied in college or university, and provides links to prose overview articles and their corresponding outlines.
* [[Outline of knowledge]] is the top-level outline, its subject being the broadest one of all. It is the ancestor of all other outlines, and they branch out from it, in successive levels.
