Subject Guides

UC Davis librarians have prepared lists of key resources for researchers in specific subject areas, to help you navigate the vast amount of information available through the library and beyond.

Subject Databases

Curated collections of articles, data, grey literature, and other resources, indexed to facilitate searching by researchers in specific subject areas.  These collections may contain resources that you cannot find by searching the open internet (e.g. via Google or Google Scholar).  Key resources for agriculture and related fields are listed here.

Search Tips for Extension Publications

Guide to searching for Cooperative Extension documents from any state, developed by a librarian at Michigan State University.

CAB Abstracts [via Ovid]

“AgEcon Search – Research in Agricultural and Applied Economics” is a World Wide Web site developed and maintained at the University of Minnesota by Magrath Library and the Department of Applied Economics. AgEcon Search collects, indexes, and electronically distributes full text copies of scholarly research in the broadly defined field of agricultural economics including sub disciplines such as agribusiness, food supply, natural resource economics, environmental economics, policy issues, agricultural trade, and economic development. AgEcon Search will serve as the permanent archive for this literature and encourages authors and organizations to use this electronic library as the storehouse for additional appropriate scholarly electronic works.”


UCD Library Catalog

Search Catalog for items held in the UC Davis Library.  This includes  books and ebooks, journals, maps, government documents, films, musical scores, manuscripts and photos.  Start with Advanced Search, and use Browse Search to see resources organized by subject.


LINK IT!  TEMPORARY ONLINE ACCESS is available for some print-only UCD materials.  Look for the gray elephant icon with the link label “Full Text Available at HathiTrust.” Also, note that the “Physical copy is Library Use Only”.  Follow the HathiTrust link and login using your UCD credentials.   Due to copyright restrictions, this service will likely be discontinued with campus re-opening in Fall 2021.

SHIP IT!  NEED a PRINT ONLY ITEM AND CANNOT COME TO CAMPUS?  We’ll ship it to you!  The UCD Libraries have a COVID-time-only shipping service in place.   While in the catalog, log in using your UCD login/Kerberos passphrase and click on the REQUEST link from the item you need and we’ll mail the whole item to you.  Make sure you have your correct address listed, when prompted.   This shipping service has always been available for researchers not based at the UC Davis campus but has become simplified through a new process in the UCD Library Catalog.

SCAN IT! ONLY NEED a chapter or an article from a PRINT ONLY ITEM?  Scanning service opened up for all during COVID TIME.  Use the same INTERLIBRARY REQUEST link but make a note of the specific chapter/article you need and include as much info as you can, especially page number, if available.  This scanning service has always been available for researchers not based at the UC Davis campus but has become simplified through a new process in the UCD Library Catalog or you can use the UCD-eLinks from a subject database search.

COVID TIME DUE DATES EXTENSION:    For any items “checked out, due dates are being extended indefinitely. If you are in the [UCD] area and would like to return materials, you can deposit returns via the remote book drops or at Shields or Blaisdell Medical Library. Materials may also be mailed back at no cost to you. Contact shieldsinterloan@ucdavis.edu for additional instructions and to receive a postage-paid mailing label.”


All UC Libraries Catalog (Melvyl) 

Search physical resources (e.g. print books) held by any UC campus.  Currently entire book delivery between campuses is on hiatus but chapters or sections of resources can scanned and sent via REQUEST.  Electronic resources licensed just by an individual campus are NOT accessible to other campuses.  For example, UCD has the only food sciences, veterinary sciences, viticulture and enology programs in the UC and buys e-resources just for those programs.  We do NOT license for the whole UC but just for our campus and therefore no-one from other 9 UCs have access to these.   Vice-versa for resources other UC libraries buy just for their own campus.   This will be particularly noticeable for UCB or UCLA but in the Agricultural area, it is very likely the UCD libraries will own the item.   If you see something important that is online but NOT at UCD, please fill out a Purchase Recommendation form to have online copy purchased:

PLEASE NOTE that MELVYL will be retired after July 27, 2021.   A new shared UC-wide Library system, UC Library Search, will be available after that date.

Here are links to online collections of information resources in agriculture and related fields, including digitized UC Cooperative Extension publications.

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.

**Note: each volume is cataloged separately. To find everything in the series, choose the “Advanced Search” option, and enter the publication name and the phrase “California Agricultural Experiment Station”.

A collection of CAES publications is also available in the Internet Archive. It contains:

Bulletin series, 1884 to 1983.


Published from 1903-1974, Circulars are the third series produced by the California Agricultural Experiment Station.  It was intended for distribution only as called for by those specially interested in the subjects embraced in them. From 1921-1951 the Circular was supplemented by the Extension Circular, which was subsequently absorbed by Circular to become the California Agricultural Experiment Station Extension Service, Circular.

A. P. Giannini Foundation Research Report Series

The Giannini Foundation of Agricultural Economics promotes and supports research and outreach activities in agricultural economics and rural development relevant to California.  Members of the Giannini Foundation are University of California faculty and Cooperative Extension specialists in agricultural and resource economics on the Berkeley, Davis, and Riverside campuses. Established in 1930.
