A library is a special Dreamweaver file containing a collection of individual assets or copies of assets that you can place in your web pages. The assets in a library are called library items. Items that you can store in a library include images, tables, sounds, and Flash files. You can automatically update all the pages that use a library item whenever you edit the item.

For example, suppose you’re building a large site for a company that wants a slogan to appear on every page. You can create a library item to contain the slogan and use that library item on every page. If the slogan changes, you can change the library item and automatically update every page that uses it.

Dreamweaver stores library items in a Library folder within the local root folder for each site. Each site has its own library.

You can create a library item from any element in the body section of a document, including text, tables, forms, Java applets, plug‑ins, ActiveX elements, navigation bars, and images.

For linked items such as images, the library stores only a reference to the item. The original file must remain at the specified location for the library item to work correctly.
