Start with the DELCAT single search box (see above) to find books, journals and media held by the University of Delaware Library as well as material held by other libraries worldwide. You can then manipulate your results by using facets such as format, subject, author, or date.
In the Advanced Search interface, you have more options in combining your search terms and in limiting your search to specific fields (Title, Author, Subject, etc.). Searching by subject can be very helpful to focus the results. Look at the subject headings listed in your results to find applicable terms. Below are a few examples of subject headings in plant and soil science.
* Plant Physiology
* Crops--Disease and Pest Resistance
