Where can I go on the internet and find out the history of say a building or plot of land?

Answer 1

sadly, there is no one stop site on the internet for this kind of information...and there is a reason for it. that kind of information is usually filed in count houses or other goverment record storage facilities for the local government..and putting all these peper documents online is expensive.

your best bet is to go to the local government center and look for the public records.
