In this chapter we covered the new and enhanced features of SharePoint 2007 that support advanced document management. We began by introducing the differences between informal and formal communication and the importance of identifying their roles in the organization. We then explored the new features of document libraries in SharePoint 2007, including uploading and accessing documents as well as configuring document versioning. We next discussed how to add custom columns to document libraries to support additional metadata for documents, and we looked at incorporating workflows into your document management system. We also examined ways in which you can manage the user experience of browsing document libraries in the Open and Save As dialog boxes by Group Policy Administrative Templates. Finally, we discussed new security features of the 2007 Microsoft Office system such as digital signatures and item-level permissions in document libraries. In the next chapter, we will expand on these concepts by examining the new records management features of SharePoint 2007.
