In our databases, there is a full-text article from 2004 entitled Protecting the Ohlone Shellmounds of Berkeley, San Bruno, and Emeryville, but you need to be an Ohlone College student to gain access to it from off campus. If you are not, you are welcome to visit either the Fremont campus library or the Newark campus LRC to gain access.
The Alameda County Public Library offers a guide to their collection and other Ohlone/Coastanoan Indian resources which you might want to explore. Let us know if you have any other questions.
