Summary
Review of what you've learned
Wikipedia is a big place!
For a start, there are currently 7 million articles, the most extensive encyclopedia in human history. If we printed them all out, they would take up about 3,697 volumes, which would look something like this.
In addition to this, there are another 56.4 million supporting pages devoted to helping build the project.
This tutorial will help you to get your bearings, teach you how to find what you're looking for, and introduce you to a few of the most important pages.
