In late 1904 Oxnard's first mayor, Richard B. Haydock, wrote a letter to
Andrew Carnegie soliciting a donation to build a library in Oxnard. In February 1906, Carnegie offered to donate $10,000 toward the construction of a library if the City of Oxnard would furnish the site and agree to provide at least $1,000 per year to maintain it. By September 1906, construction was underway. Mayor Haydock selected the Greek Neo-Classical architecture with Doric columns for the new library, which was designed by Los Angeles architect
Franklin Burnham. Carnegie initially gave $10,000 toward construction of the library, but as the plans were drawn, the city decided to build a more expensive building that could also house the city's municipal offices and city hall. In July 1906, the city signed a contract with Thomas Carroll for $14,000 to build the dual-use facility. Carnegie agreed to pay half of the additional appropriation in addition to the original $10,000 gift. The main floor was occupied by the library, and the basement was Oxnard's city hall. The library was opened on May 16, 1907. Five years later, Oxnard's library had "the largest circulation of any city of the sixth class in the State." In 1923, the library was expanded with the opening of a new three-story addition on the east side of the building, allowing the library to expand its holdings to 20,000 books. ==Later uses==
