University Libraries buys many materials that can be used in scholarly research. These can be in print or electronic format.  Use the Library catalog to find them.

Other libraries might have sources not owned by University Libraries. Use Prospector to identify sources from such institutions as University of Colorado at Boulder or Colorado State University, as well as other academic libraries in Colorado. Material requested through Prospector takes about 3-5 working days to receive, as long as the item is available. Use WorldCat if you are going beyond the area covered by Prospector.  Be sure to give yourself the quarter for obtaining material identified in WorldCat.
