With a single search, identify relevant content in many online and print reference sources (encyclopedias and more) that are available through the CSU Libraries.
To search, type simple words/phrases (e.g. feminism; sustain*; birth order).
These are just a few of the reference resources we have to offer. Check the library catalog for more. Do a general keyword search and limit your search to Location --> Reference to find the titles that provide background information about your topic.
