Encyclopedias are a good place to find short summaries on a topic. They often give good background information about your research topic.
Use the Quick Search box on the Library homepage to find research materials owned by the ISU Library. Be sure to change the first dropdown box to say "books."
The record includes a description and location information for books and other items owned by the Library.
You will need the book's call number in order to find the book in the Library.
