“The long-awaited modernization of the library is nearing completion, and people will be amazed how the changes enhance functionality and elegance while retaining the late 20th Century beauty of the interior,” Petaluma Regional Library Manager Diana Spaulding said. “The library staff eagerly anticipates welcoming the local community of readers (and pre-readers!) into the library to enjoy the expansive library collections, four small group and individual study rooms, and many tables powered for personal laptop use, among other improvements.”

About Petaluma Regional Library

Petaluma’s first library was an Odd Fellows Library established in 1858. By 1878, its ownership was transferred to the City of Petaluma as part of the Rogers Free Library Act and the library was relocated to the upper floor of City Hall.

In 1906, the Petaluma Library opened at Fourth and B Streets. The Carnegie library was designed by local architect Brainerd Jones and built from locally quarried stone. The building features the largest freestanding leaded glass dome in Northern California. With few changes through the decades, the building served as a Carnegie Free Library until 1976. In 1988, it was listed on the National Register of Historic Places. It is now the Petaluma Museum, a historical museum with a research library.

By the late 1950s, increased usage and limited space demonstrated the need for a larger facility with space to provide modern library services. Studies indicated that alternate solutions, such as enlarging the old building or opening a small east-side branch, would not be feasible. In three elections, bond proposals for a new library failed to get the needed two-thirds vote.

In 1973, as population and demand grew, the need for a new facility increased and a plan for a more centrally located building was developed. With the commitment by the city council and the county board of supervisors to allocate federal funds to cover half the cost, a bond issue for the balance was approved in a special election in 1974.

The new library, located at the corner of East Washington Street and Fairgrounds Drive, opened in 1976. The Petaluma Regional Library spans over 25,000 square feet and features exposed heavy timber trusses and natural wood finished walls. The library is constructed with brick-veneered walls and a copper roof. Several improvements have been made in recent years, including expansion of the Forum Room, and creation of a bookstore that is operated by the Friends of the Petaluma Library.
