California Agricultural Resources Archive (CARA)

Digital collection of materials on crop research, agricultural production, technology, land use, socioeconomic development, 4-H and youth development, among other subjects, from the County Offices of the UC Cooperative Extension Service.  A built-in search tool locates UCANR publications across several online databases, including Calisphere, Hathi Trust, and Internet Archive.


Calisphere “provides free access to unique and historically important artifacts for research, teaching, and curious exploration [which have been] digitized and contributed by all ten campuses of the University of California and other important libraries, archives, and museums throughout the state“.

Online Archive of California

“The OAC is a website that provides free public access to detailed descriptions [and in some cases digital copies] of primary source collections (artwork, manuscripts, papers, historic photographs, and so on) maintained by more than 200 libraries, special collections, archives, historical societies, and museums throughout California — including collections maintained by the 10 University of California (UC) campuses”.


ArchiveGrid provides descriptions of documents, personal papers, family histories, and other archival materials held by thousands of libraries, museums, historical societies, and archives. The majority of the records are from US institutions, and were harvested from WorldCat.


Hilgardia was the primary technical publication of University of California Division of Agriculture and Natural Resources for 70 years, published from 1925 to 1995.  The full series has been digitized.

California Agricultural Experiment Station Publications

The following CAES publications have been digitized, and can be found in the catalog of the UC Davis Library: Bulletin, Circular, Extension Service Circular, Lithoprint, Manual, and Publications in Agricultural Sciences.
