Are free public record sites really free?

[Alfredo GonzalezC]

Hi, I have been trying to find free public record information like foreclosures or tax liens issues properties in my area. I have tried a couple of links that says Free Public record information and all of them tun out to be not public at all at the end.

Does anybody know of any website that actually offer this kind of free information. 

If not, is there a trustable website that can be used for this purpose even though is not free?

Thanks,
