The library maintains several research guides that might be useful for EEPSA students. You can find an overview of the research guides at: http://guides.lib.udel.edu/
Two research guides stand out in their particular usefulness for EEPSA students: Energy (http://guides.lib.udel.edu/energy) and Environment (http://guides.lib.udel.edu/content.php?pid=163876)
These research guides detail on resources, journals, databases, etc. appropriate for their topic.
