This guide is designed to provide research support for History 400: U.S. Environmental History in the 20th Century (Fall 2023, McCommons) by identifying research resources of potential interest. This site is not meant to be exhaustive, but it should serve as an entry point into possible topics to be considered for research projects. Please feel free to schedule an appointment with Lynda Kachurek, the history liaison librarian, for more specific research assistance or if you have questions!
