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.
To find secondary sources in book form, search the library catalogs: OskiCat or MELVYL (about). To find articles that are secondary sources, search an article database, such as America: History and Life (US and Canada) or Historical Abstracts (world history).
Primary sources may be physically located in any of a number of UC Berkeley Libraries, or they may be available online.

How to Use the Bancroft Library
Before you go:
1. Be prepared! Read secondary sources and know something about your topic.
2. You must register with the Aeon software to use the Bancroft Library. You may register online in advance.
2. Search UC Library Search. You can limit your search to find materials at the Bancroft Library, instead of all campus libraries (in the list of search results, choose the Library filter > Bancroft Library). Remember that there are primary sources in many other campus libraries as well. Ask for assistance from a reference librarian.
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 UC Library Search record, or you can search the Online Archive of California to find it. The finding aids that are not online are near the Registration desk at the Bancroft Library.
3. Plan your visit; you will need to bring current government-issued ID, call numbers, titles, etc. with you. You may find it convenient to bring a quarter for the lockers, and a digital camera/cameraphone. Read the Conditions of Use to learn what you can and cannot bring into the Bancroft Library.
5. While onsite, make requests to see items before 4:30 pm.
6. Ask for assistance at The Bancroft Library's reference desk, or request assistance by email.
