An example of a document library.
A SharePoint document library is a place on a site where you can create, collect, and update files with others. In this example, employees at Contoso Pharmaceuticals are using a document library called "Shared Documents." They have added files to the library, and now people can make changes to them. Those changes will be stored in the library — not on their own computers. And, because the library is on a Web site, other people can easily access the files using a Web browser, provided they have the permissions to do so.
