Q. Research access doing study of Ohlone historic presence in Misson San Francisco at current development sites
against developer disruption of present and historical Ohlone sites
I'm not entirely sure I understand your request, but let me try. We do have copies of The Ohlone Way: Indian Life in the San Francisco-Monterey Bay Area and The Costanoan/Ohlone Indians of the San Francisco and Monterey Bay Area: A Research Guide, which might cover the Ohlone presence in the Mission, but we do not possess any primary sources specific to developer disruption to Ohlone sites.
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.
