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. From the search box, choose "Library Catalog" to search just books, ebooks, films, and similar materials. Choose "Everything" to include individual journal and magazine/news articles, government documents, and HathiTrust books in your search. Use the facets on the left to limit your search to Books and, if needed, to materials Available Online. 

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.)

Some subject headings or keywords that may be helpful: 

• Colonies 
• Great Britain -- Colonies 
• Imperialism
• India -- Foreign Relations -- Great Britain [also the reverse; insert the names of whatever countries you are researching]
• Postcolonialism

If you can't find the information you need in ZSR Library's holdings in Primo, you can choose "Include Items with No Full Text" in the facets on the left side to expand your search beyond ZSR. Make sure to limit to the types of sources you want to see first (i.e. books or book chapters), so that you don't get overwhelmed by the number of results!

You can also try searching WorldCat, which includes holdings information from other libraries. You can request these books through Interlibrary Loan if you are on campus. (Remember that it may take 1-2 weeks or more for items to arrive through Interlibrary Loan, so plan ahead!) Note that libraries are not allowed to loan ebooks through Interlibrary Loan. In cases where you are unable to access the physical book, but just need a portion of the book, you may be able to request a chapter or two be scanned and emailed to you, rather than a physical copy. You can also check for full text ebooks through resources such as the Internet Archive. Contact me using the links to the right if you have questions!
