Primary sources were either created during the time period being studied or were created at a later date by a participant in the events being studied (as in the case of memoirs). They reflect the individual viewpoint of a participant or observer. Primary sources enable the researcher to get as close as possible to what actually happened during an historical event or time period
A secondary source is a work that interprets or analyzes an historical event or phenomenon. It is generally at least one step removed from the event is often based on primary sources. Examples include: scholarly or popular books and articles, reference books, and textbooks.
After you've found your primary sources, learn to analyze them using The Bancroft Library's Primary Source Analysis Exercises.
Primary sources on campus may be in their original format; examples might include:

Finding Background Information
Gather the information you have about your topic and consider what you still need to know before you start researching. You can use this information in searching for primary sources.

If the UC Library Search record mentions a finding aid (an index) to a manuscript collection, you should use it to help you find what you need in the collection. If the finding aid is online, there will be a link from the catalog record. Many of the finding aids that are not online are shelved near the Registration Desk at the Bancroft Library. You can also search for Bancroft finding aids in the Online Archive of California.
