Accessing Electronic Books

A new guide to finding electronic books within, and beyond, the UCD Library’s collection.

*Note: Access to electronic books is campus specific. Use the UC Davis library catalog, or E-book collections in the Databases list, to find and access books through the UC Davis Library.

UC Davis Library Catalog


  • Select “Library Catalog Only” to exclude articles from the search (e.g. if you want to find books, not reviews of those books).
  • Show only E-books by selecting the “Full Text Online” filter to the right of results list.
  • Browse Subject Headings, or search within the full text in Google Books (access to copyrighted materials is restricted, so use the book citation to find the book in a Library catalog).

Dissertations and Theses

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.

Ulrich’s Periodicals Directory

Expand your search from a key journal to many resources with related content, search for the journal name in Ulrich’s Periodicals Directory and look at the Abstracting and Indexing field (see below) to learn which databases include your journal of interest.  The list of databases is not directly linked from there; you will need to search for the database in a library Subject Guide or the Database List. You will quickly come to recognize key databases the UCD Library provides access to, and are always welcome to ask a librarian for help at this step. 



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.

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.
