OneSearch is a special tool which allows you to search multiple databases at the same time. You can choose to search all four databases at once (Photographs, Textual Records, Artifacts and Heritage Landmarks), or you can pick the combination of databases that you wish to search from the list below. By default, all databases will be automatically selected for searching. After you have selected the desired database(s), simply enter in your keyword or phrase and hit the "search" button.
A list will then be displayed below the search box showing how many results were found in each of the databases that you selected. To see the results in each database, hit "View Results".
