Taz - nice idea which will become a mammoth task. Problem is "commitment" from the "poster". I'd like to help...but...we'll lets give it a bash. Whatever. To tackle the place names it might be an idea to follow the journeys as above - but that would end up leaving a lot of stuff out (yep in the end it would!)
However, if, with Grondmaster's help and a few good bokks, we did things like ordonnace surveyors - take the maps and go through each area, in detail. Of course then you would have to cross reference the differnet geography according to the different ages etc.
For starter though a complete geography (scientific stuff) oif Hobbit and LOTR would be a good task
Well thats my feeling
Problem is - anyone know anything about topography or geography anymore?
