Reference works are a great way to begin researching a topic which may be new and unfamiliar to you. This page contains a number of general works you can access to begin your research related to agriculture and the environment. There are also links at the bottom of the page to a sampling of journals, as well as additional tabs to research databases, where you can then explore more specific and detailed research questions and topics.
The information you discover in reference works can be very helpful for developing more specific topic searches in research journals and databases.
Many encyclopedia articles have additional reading materials cited that can jump start your search for more in-depth information on a given topic.
