It represents the work of William Corlett, a locally prominent architect who worked in several styles. It also anchors an unaltered cluster of churches and schools near the Main Street commercial district.","narrative":"Built in 1907 at the corner of Adams Street and Oak Avenue, this two-story library with a ground-level basement has served St. Helena continuously as a library. Architect William Corlett of Napa gave it Mission Revival features: stucco walls with decorative tie-rods, curvilinear gables and dormers, exposed rafters under projecting eaves, and semicircular arched windows and doorway. It was the town's first dedicated library building. Earlier library services had used several sites, including a front room of the Oddfellows Building in 1886. A $7,500 grant from Andrew Carnegie paid for it, on condition that the city buy a site and pledge upkeep, which a local bond issue covered. It is the only Mission Revival civic building in St. Helena, and Corlett also designed the Star Building and the Richie Block nearby. The library sits among churches and schools that have kept their relationship since the early 1900s. A replacement library was planned for 1979, leaving the building's future use uncertain.","period_of_significance":"1907","architect_builder":"William Corlett","architectural_style":"Mission Revival","criteria":[],"status_note":"Described as in excellent condition and unaltered since 1907, in continuous use as a library; a new library was due in 1979 on another site, and future use of the building was uncertain.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:31.419446-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/79000509.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79000509/8080bf76eb-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79000509/8080bf76eb-1600.webp","licence":"CC BY-SA 3.0","author":"Sanfranman59","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:St._Helena_Public_Library,_1360_Oak_Ave.,_St._Helena,_CA_10-16-2011_1-05-10_PM.JPG\" rel=\"noopener\">Sanfranman59</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:St._Helena_Public_Library,_1360_Oak_Ave.,_St._Helena,_CA_10-16-2011_1-05-10_PM.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123860102","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q58126363"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/napa-county/st-helena-public-library-79000509/"}
