What Is a Document Library?

A document library a special instance of a list, in which every list item is a file.

Files can be Microsoft Office documents, Adobe Acrobat documents (PDF files), or any other type of file that the system administrator allows.

Most of the attributes of lists exist in document libraries. In fact, lists and documents libraries are similar in many ways. However, each item in a document library is a file. Therefore, when creating a new item in a document library, you need to either upload a file or create one.
