About This Collection

This collection offers a selection of historical Sonoma County maps held by the Sonoma County Library. It includes township maps, plat maps and more. We have many more maps than are viewable on this site and will be making additional maps available in the future.

Maps and Streetview

The Google maps and Streetview images displayed below many of the Collection's images are based on the best information available in the records. In some cases, that information may be incorrect or Google was unable to interpret the address correctly (more than a few street names have changed over time and lots may have been renumbered). If you find an incorrect location for a particular image, we welcome corrections! Please use the comment feature at the bottom of the page and provide more accurate information if you have it. We verify the corrections and update our information.

Unknown Locations and Subjects

We also welcome information on unidentified locations and people in our collections -- unfortunately, we have many such images . If you know something more, leave a comment on this site or at our Flickr collection of unidentified images .
