If you are working for a publication – high school or college – you should not use maps created by MapQuest or some other professional service without specific permission from that service. To do so is a violation of copyright laws.
Maps that are free from those restrictions are available from other sources, however. For national and state maps, try the U.S. Census Bureau. For local maps, look on the web sites of city and county governments.
University libraries and geography departments often create maps of the areas they serve, and those can often be used without permission. Before using any map, check to make sure there are no restrictions on its use.
