The UVM libraries has loads of resources that you can use to locate high quality resources related to the issues you're discussing in your class that cannot be found on the "open web." As you conduct your research try to use a variety of tools to help you locate materials as each will find different things (although there may be some crossover).
For ease of use this guide is set up to highlight types of materials you may want to use. Simply go to each tab for more information.
If you need more help with your research, please contact me. You can e-mail me or schedule an appointment with me by using my online scheduler.
