Our mission is to preserve, protect, and provide public access to the records and heritage of Contra Costa County.

The 2017 Scan-a-thon is coming

Saturday, March 18, 2017 10:00 A.M. - 3:00 P.M.

Become a Part of Contra Costa County History! Bring your treasured Photos, Documents and Letters to our Scan-a-Thon on Saturday, March 18th, from 10:00 a.m. to 3:00 p.m.

The Contra Costa County Historical Society is hosting a scanning event. Bring in your photographs, negatives, documents and letters to the Scan-a-thon so we may scan them for possible inclusion into our database.

Scanning technicians will help guests make archival digital scans, give a copy for guests to take home, and keep a copy for public access in CCC Historical Society’s digital archive. Volunteers will also take down names, dates and places to set each photo’s context, and provide this detail along with your digital images. Over-sized documents as large as 16” x 24” and negatives up to 5” x 5” are easy to do with our large format scanner.

Additional details:

We specialize in fragile, delicate photographs, documents and letters! Photographs, documents, and letters contain invaluable clues to the history of Contra Costa County. Let our experts help preserve them.

CCCHS video at Lesher Foundation "Newsmakers" Speaker Series

On November 2, 2015, the Contra Costa County Historical Society was chosen to be the non-profit "partner" for that night's lecture in the "Newsmakers: Lesher Speaker Series" held at the Lesher Center in Walnut Creek. In addition to a generous donation of event tickets to the society, media sponsor KTVU Channel 2 sent a video crew to the Center to make a video highlighting some of our accomplishments. The 2 1/2 minute video was screened to the audience at the event, and a copy of the finished product was given to the Society to use as it sees fit. You may see the video shown that night by clicking on this link.

Looking for a gift for that hard-to-buy for history buff? The History Center offers a wide variety of books, photographs and services that they will just love. A membership in the Contra Costa County Historical Society makes a great gift too. For details on Society membership, whether for yourself or as a gift, please click here.

We are using the World Wide Web in order to give more of us access to the wonderful stories of the people who lived in our County, so many years ago.
