ADL Library Webclient - Map Browser

The Map Browser provides a world map that you can use to focus a search on a particular location. The visible portion of the map is the search area.

You can set the search area by panning and zooming the Map Browser or by typing in the latitude and longitude coordinates directly into the Geographic Region portion of the Catalog Search window.
