There is no one source you can use to search the entire run of the Daily Cal; to find articles on your topic you'll need to use an index. Complicating matters is that the index to the Daily Cal has changed format many times, so where you look depends on the time period you are interested in.

Newspapers on Microfilm
Because of their fragility as they age, newspapers have traditionally been preserved by microfilming them.
Microfilm must be read on microfilm reader/printers. The Newspaper and Microfilm Room in 40 Doe Library has them. So does Bancroft Library. Newspaper films are arranged geographically within the News/Micro collection [floorplan.pdf]
Reader/printers allow you to read the films and those in News/Micro allow you to save pages to flash drives in .jpg and .pdf format.
Most newspapers do not have indexes. How do you find articles by subject? By knowing the approximate date of the event you are studying. If you don't know the date, you can use the index to a different newspaper as a way to find out.
The Library has only a few online sources for newspapers covering the 1960s, and the only California title we own for that period is the Los Angeles Times, which can be accessed through Historical Newspapers (Proquest).
In News/Micro you will find microfilm of many California newspapers. Few of them are indexed so you should prepare before your visit a list of dates of issues that you want to look at.
The San Francisco Chronicle is available full text online only up to 1922. Indexes for other years are available in News/Micro:
