Library Items and Templates are Dreamweaver features that enable you to easily maintain a consistent look and feel throughout your web site. The central principle behind these assets is single-source editing. When you make a change to a library item, Dreamweaver updates that library item on all pages where it is used. When you make a change to a template, Dreamweaver updates all pages based upon that template without affecting any of the unique content on the individual pages.

If your goal is to manage a site effectively in Dreamweaver, taking advantage of these assets is key. Other site-management strategies include dealing with multiple content developers working with the same site, working with the site from multiple locations, and managing your site with Dreamweaver's File Check In / Out system.
