Library Home > Databases > Search for “Dissertation” > ProQuest Dissertations & Theses 

This proprietary database helps you locate dissertations published since 1861 (theses began to be added later), which are usually only held at the institution where the degree was conferred.  Sometimes, hard copies are available for interlibrary loan. A digital copy of works published after 1997 is available for purchase (you can suggest the library acquire it for our collection), or for free if the home institution is a UC campus.

Agricultural Statistics Guide

Global agricultural statistics (FAOStat)

Agricultural production data from the Food and Agriculture Organization of the United Nations.

Example: Data > Producer Prices > [choose a crop, year, country]

International Network of Food Data Systems (INFOODS)

Composition data for foods.

Example: Tables and Databases > [choose a user guide to view contents]

US National Agricultural Statistics Service

The NASS Quick Stats Database is the most comprehensive tool for accessing agricultural data published by NASS. It allows you to customize your query by commodity, location, or time period.

Example: survey > crops > field crops > hops

Industry Groups

Industry groups often collect or repackage production and price data relevant to their membership. For example, the California Strawberry Commission releases various reports on the current and historical status of the strawberry market in the U.S., derived from both public and private data sources.

UC Davis Library Special Collections

Here is a list highlighting some archival collections relevant to the plant sciences.

Collections Related to Plant Breeding

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 the most comprehensive shared library catalog available to us, WorldCat.

Genomic and Molecular Information

The Arabadopsis Information Resource (VPN connection required)

The Arabidopsis Information Resource (TAIR) maintains a database of genetic and molecular biology data for the model higher plant Arabidopsis thaliana . Data available from TAIR includes the complete genome sequence along with gene structure, gene product information, gene expression, DNA and seed stocks, genome maps, genetic and physical markers, publications, and information about the Arabidopsis research community. Gene product function data is updated every week from the latest published research literature and community data submissions. TAIR also provides extensive linkouts from data pages to other Arabidopsis resources.

Repbase (VPN connection required)

A database of representative repetitive sequences from eukaryotic species. According to its producer, Repbase is being used worldwide as the reference standard for annotating the presence of repetitive DNA in genomic data. Newly identified repetitive DNA elements reported in the monthly e-journal, Repbase Reports, are stored and shared in the Repbase database.
