Wikipedia is an encyclopedia, that explains millions of things about the world, the people and things on it, and beyond. There are 2 ways to look things up in Wikipedia: by searching or by browsing...

If you know the name of the topic you are looking for, simply type it into Wikipedia's search box, press ↵ Enter, or click on the magnifying glass.

If you would like to look around Wikipedia to see what is on it, keep in mind that many major subjects have a root article on the Portal:Contents/Overviews page, and an outline listed at Portal:Contents/Outlines.

There are some other "Tables of Contents" type pages on Wikipedia. They are:

• Portal:Contents/Portals – portals provide a digest of excerpts and things to do
• Portal:Contents/Lists – item lists like List of dog breeds
• Portal:Contents/Glossaries – alphabetized lists of definitions

Wikipedia also has an alphabetical index of all of its articles, and a categorical index of most of them.
