A document library is a SharePoint list with the capability to store documents. In many organizations, e-mail, file shares, and desktops are used to store or share files, and this is adequate when there is only a single user or a few users of a particular document. This solution starts to be less effective when collaborating with other users on a document. To effectively collaborate, we need metadata (columns), versioning, search, workflows, and required check out to ensure a single version of the truth. The default document library template automatically collects metadata such as title, created by, date created, modified, and date modified. The document library templates are described in Table 3.2.
