Books are shelved in general subject categories using the Library of Congress classification system. You may want to supplement your use of the catalog with browsing shelf areas for your topic.
Most relevant materials can be found in the "GE,” “GF,” or "QC" call number ranges.
Because environmental studies is a wide and inter-disciplinary field, useful resources can also be found in other subject areas, including ecology and environmental science, as well as ethics, law, economics, and pollution control.
