# Step 2: Choose a Data Set to Search

Using the [Sources Menu](/navigating-and-searching/data-sets-and-sources.md) (Accessed under 'Choose a Data Set'), you can narrow your search to specific Object types in the Census database by clicking on the relevant boxes: 'Antique Monument', 'Postclassical Work', or both 'Antique Monument' and 'Postclassical Work'.

Make sure as well that "Census" is selected under Pools.

IMPORTANT: Selecting the data you wish to search is an important step. Make sure that you select Antique Monument, Postclassical Work, or both. Ensure that "Census" is checked under pools.

You can also optionally search the secondary Object types (Period, Location, Image, Person, Style, and Bibliography) by clicking on the relevant icons in the left-hand menu bar.
