Where on Middle earth am I?

[Hookbill the Goomba]

First question;

Right, this has been annoying me for some time now. WHERE IS BELERIAND? I ask this because I have heard two different things about it. Firstly in The Atlas of Middle earth (which I purchased recently), it says that Beleriand was destroyed in some way. That would seem to tie in to what is said in HoME X (or 10 for all you non-Roman people) as to the change from a flat world to a round world and the reshaping of Middle earth.
However, in other books such as "Characters form Tolkien" Beleriand is shown to be slightly to the north of the area of Middle earth involved in LoTR. (If you have no idea of what i am on about, go home... or look here )

Also I have been told that in other HoME books that I have not got, it says that this is what is right. Does anyone have the answer? Or is this going to cause too many arguments and deaths. (Technically this is the barrow downs and we are all supposed to be dead and well...)

Second question;
There is no second question.
i was going to put one, but i forgot what it was... You think of one...
