Research
“Research is formalized curiosity. It is poking and prying with a purpose.”
- Zora Neale Hurston
The History Center is open to the public for research during regular business hours with a volunteer staff that is happy to assist you with your research studies.
Research services can be arranged by email (info@cocohistory.org), telephone (925-229-1042), mail (724 Escobar St., Martinez, CA 94553) or the online research form found at the bottom of this page.
Once your Research Query is received, a staff member will review the Society's research databases and collections and advise you if we can help. This initial consultation is free.
Research services are free for official representatives of Contra Costa County government agencies and departments; public schools and school districts within Contra Costa County and their teachers; public school students doing classwork for schools within the county.
For a complete list of services and fees, please refer to the Fee Schedule PDF in the next section.
Our archive covers a vast range of the County's life assembled from our collections of newspapers, obituaries, court, and judicial records (e.g. naturalization, probates), photos, maps, school histories, our library collection, and various special collections.

Research Inquiries
Research inquiries can be made by phone, email, or filling out the research question form below. Please be specific in your request, including the names, dates, and locations of your subject within Contra Costa County. Our researchers will check the collections first before responding with a quotation of any fees for research and copying.
Please be specific to names, dates or timeframes, and known locations in the county and the question(s) to be answered. The more we understand your needs, the better we can serve you. For example, “family research” is vague but “Jones Family Research", particularly "Jonas P. Jones” is better.
Research Fees
The Society charges fees for some of the services and products we offer. We charge these fees to recover our costs and help fund our continued operations. Some fees are lower for members of CCCHS and the full list of services and fees are listed here in our Fee Schedule.
If your research will involve fees, the exact amount will be determined by the staff person who assists you. Fees may be paid by cash, check or credit card. If you have further questions about the fees we charge, please contact us.
