Earth and Resource Science is an interdisciplinary science. It includes Sustainability, Resource Planning, Geology, Geography, Environmental Science and Geographic Information Systems.
As with most physical sciences, research usually starts with journal articles. There is a "quick and dirty" search box below that will bring up articles on your topic. Or, you can use the other Tabs on this research guide to start researching the area you are interested in.
If you're not sure where to start contact the liaison librarian to get you going.
