SharePoint gives users the ability to intermix content sources in document libraries by leveraging the Link to a Document content type. This seemingly little known out-of-the-box component allows site owners and designers to create concise, clean content libraries with ease. Owners and designers can leverage existing site columns and metadata by extending the base content type to suit the needs of the department or organization. This gives users the ability to sort and filter information in these content sources as needed to accomplish their day–to-day activities.
