# The Side Bar: Secondary Object Types

On the left-hand side bar, you will also find icons that represent the secondary Object types, Bibliography, Period, Location, Person, Style and Image:

To search the data in the Census related to one of these Object types, click on one of these icons. You can then carry out a search using the free text search bar or the Advanced Search function.&#x20;

Unlike the Primary Object types (Antique Monument and Postclassical Work), these categories can only be searched singly, not in combination.
