The Encyclopedia's contents

Shortcuts: WP:CONTENTS WP:START

There are two ways to look things up in The Encyclopedia: by searching or by browsing.

If you know the name of an article for which you are looking, simply type it into The Encyclopedia's search box and press Go, or you can search for information on a topic by typing it in the box and selecting Search.

If you would like to look around the encyclopedia to see what is on it, use The Encyclopedia's Contents pages. Lists and indices are examples of contents for a published work, and The Encyclopedia has many of each, including a complete alphabetical index and indices by category.
Links to all of The Encyclopedia's main contents pages are presented below, and they in turn link to the more specific pages.

Overviews of The Encyclopedia

An overview is a survey of what is covered in an area. Overviews of The Encyclopedia's coverage include:

Outline of Knowledge—a set of outlines combined to provide a guide to The Encyclopedia's content. Each outline shows the structure of its subject and serves as a table of contents to its coverage on The Encyclopedia.
Overviews—a one-page outline of the contents of The Encyclopedia, covering 12 major subjects, providing links to key articles in each.
List of academic disciplines—The Encyclopedia arranged like a college course curriculum.

Lists

The Encyclopedia has thousands of topic lists; some are even lists of other lists.

Lists of topics—a selective collection of article lists, arranged by subject.
Category:Lists—a list of lists in the category system, arranged alphabetically.

Two of the broadest collections are:

Lists of countries and many lists by country.
Lists of people including by nationality and by occupation.

Portals

A portal is an introductory page for a given topic. It complements the main article of the subject by introducing the reader to key articles, images, and categories that further describe the subject. They also include to-do lists that are used mostly by The Encyclopedia's editors.

Portals can be found at:

List of portals—a list of active portals.
Category:Portals—portals in the category and subcategories, arranged alphabetically.

Glossaries

Glossaries are lists of terms with definitions:

List of glossaries—a list of glossaries arranged by subject.
Category:Glossaries—glossaries in the category and subcategories, arranged alphabetically.

Timelines

Timelines are lists of articles organized chronologically. These are the top-level timelines and lists of timelines:

List of timelines—a selection of historical timelines, arranged by subject. More can be found in Category:Timelines.
List of centuries—(e.g., 20th century)
List of decades—(e.g., 1910s)
List of historical anniversaries—(e.g., today).
2010—major events this year.
Portal:Current events—featured current events and related project activities.
Recent deaths—notable recent deaths, by month.
Category:Graphical timelines—graphical timelines in the category and subcategories, arranged alphabetically.

The Encyclopedia's indices

Alphabetical indices

Complete alphabetical index—sorted by the first two letters of the title, e.g., "Aa Ab Ac Ad..."

Categorical indices

The Encyclopedia's main categorical index system is automatically generated from information (category tags) at the bottom of each article. The top-end pages of the category system are:

Categorical index – an index of major categories, arranged by subject – that section of the page is an exception to the category autogeneration rule, as it is crafted by hand.
Category:Categories—the highest level or "root" category in The Encyclopedia – its autogenerated entries are listed at the bottom of the page.
Category:Contents—the category equivalent to this page.
Category:Articles—the category in which all article category systems are located.
Special:Categories—every category listed alphabetically.
Category:Fundamental— the category containing the most fundamental ontological categories such that every article category system can reasonably be expected to be within it.

The Encyclopedia's other broad categorical indices are:

List of Dewey Decimal classes—lists the top two levels of this library classification system.
Library of Congress Classification—this article provides a reflection of its own deep linkage structure.
The Encyclopedia:Outline of Roget's Thesaurus—articles organised into a system based on six classes, with thousands of branches, following Roget's system.
