You can create search boxes for specific Gale Databases by going to the Gale Widgets webpage and signing in where it asks for the location ID.
For AVL databases enter:
Location ID: naal_aub
For Auburn subscribed databases or purchased archives enter:
Location ID: aubu72210
Click on the View Your Products Button
Select the database or collection you want.
Here you'll find icons, links, publicity material, and the code for your widget.
Search boxes can only be created for an individual Gale Resource -- The Opposing Viewpoints in Context search was created using the naal_aub location. You don't have to worry about the proxy the widget maker takes care of that for you.
