LibrarySearch, our primary catalog searches our holdings as well as those of our Summit partner academic libraries here in the Pacific Northwest. When you search "UO+Summit" you will see items matching your search held in the UO Libraries, then items held in Summit libraries.
These databases provide access to excellent secondary sources, especially from academic journals, relevant to this class. For the best, most comprehensive results search multiple databases since they all cover different journals.
These databases, websites, and specialized catalogs of primary source materials will help you to track down the materials you need for your projects, often in digital full text.
