Other libraries might have sources useful for various topics. For example, public libraries are more disposed to purchase books on how to set up a type of business than academic libraries. Use Prospector to identify sources from such institutions as Denver Public Library or Boulder Public Library, as well as other academic libraries in Colorado. Material requested through Prospector takes about 3-5 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.
