Use Primo to locate materials available through ZSR Library. Search by keyword, author, title, or subject, or use the Advanced Search option to combine these features. There are two search options: 

• "Everything" searches books and ebooks, individual chapters, individual journal and magazine/news articles, government documents, HathiTrust books
• "Library Catalog" limits your search to books, ebooks, films, and similar materials.

Use the facets on the left to limit your results to certain item types, date ranges, etc.

Books may serve as either primary or secondary sources, depending on the content and when they were written. Books may also contain references to primary source material in the text or in the bibliography. 

You can start with a keyword search to identify relevant items. From there, look at the subject headings used to describe that item to identify other potential items (click on the subject heading to see all other items that are tagged with that subject). 

Example:

To locate potential primary sources, use the Advanced Search option to search in the Genre field for items that contain the generic term, sources, or more specific terms such as diaries, letters, correspondence, autobiography, interviews, or personal narratives. (This option is only available in the Library Catalog search.)
