If you need to look up something in the US Census. Pretty much all the big genealogy sites can help you. However, it takes time to put all the information in and then look through the images. It turns out there are simple and quick ways to look up something in the census.
One such site is here. Created by Steve Morse, it'll use the FamilySearch as an engine to search census records and then you can look at just one item rather than a giant list. You'll need a free FamilySearch registration, but you can get that "special" record quickly and easily.
