In order to thoroughly exhaust the literature for your research, you will probably need to access some sources that are not available here in the CSU Library. You can use the online tool, WorldCat, to do this. Worldcat is an online catalog that allows you to search the collections of thousands of libraries from across the globe.
Most libraries have outside patron policies and will permit you to use their resources within the building and will often allow you to obtain digital copies of articles or copy or print any articles you need.
See How to Use WorldCat for instructions on searching within this resource.
