The beginning of 2014 begins my 35th year of world building and map making. Finding a good resource(s) for both world creation and creating maps has always been difficult. The following list has made my life easier creating worlds and creating maps.

The Library
Either your local library or via the net, finding books and examples of maps you do not have to pay for to look at will make life easier

A Used Book Store:
Anyone who is into World Building or Creating a Map should get a world atlas. They an cost a great deal of money new. Going to a Used Book Store you can purchased a 5 or 10 year old atlas for pennies on the dollar. I am still using a Wold Atlas from an encyclopedia set that is over 30 years old.

Any other suggestions?
