How to create a document library in SharePoint 2010

A Library is a list where each item in the list refers to a file that is stored in SharePoint. Libraries have all the same behaviors as lists, but because libraries contain files, they have extra features. One of these is the ability to be opened and modified through a compatible WebDAV client (e.g. Windows Explorer).
Microsoft SharePoint comes with some pre-defined list and library definitions. These include: Announcement Lists, Blogs, Contacts, Discussion Boards, Document Libraries, External Content (BCS) lists, Pages, Surveys, and Tasks.Some of these pre-defined lists have additional integration. For example, lists based on the contact content-type can be synced directly with Microsoft Outlook.
