The Library is used to organize the documents that comprise your content for non-presentation purposes. You use these documents to create an outline in the Outline Editor for presentation to your audience in Player or document formats. 

The Library displays two panes that are resizable by dragging the vertical bar to the left or right to view more of either pane. The Folders pane on the left shows the hierarchy of folders, and the Content pane on the right displays additional folders or the documents that are stored in a selected folder. The right pane also displays various folder or document properties such as icon and name, document type, and so on. 

 Multi-user Considerations

• As documents are checked in and out, icons appear to the left of the document name indicating the check in/out state as follows:
   
  indicates that the document is checked out to you.
   
  indicates that the document is locked and checked out to another author.
   
  No icon indicates that the document is checked in and available to any author.
   
  These icons appear in various places such as the Library and Outline Editor as well as on document editor tabs and various views. Also note that additional columns in the Details view of the Library and Outline Editor display the check in/out state and version number. The Checked Out By column displays the name of the author who is currently using the document.
