# How to check format [closed]

I am having troubles with the following data:

slavelist = ResourceData["New Orleans Slave Sales 1856-1861"]


I want to select all slaves with:

SellersStateOfOrigin == Alabama,United States


But I don't get what's the format of it. I tried the following :

Select[slavelist, #SellersStateOfOrigin == "Alabama,United States" &] but it won't work...

can someone help?
