The mapbooks quickly caught on with hunters, fishermen, hikers, canoeists, campers, and salespeople because the maps detailed virtually every road, trail, river, stream, and body of water in the state. DeLorme himself then went town to town selling The Maine Atlas and Gazetteer out of his car. Gathering data from state highway, county, and town maps as well as federal surveys, DeLorme created a state map and had 10,000 copies printed in a large-format book.
