Searching DELCAT Discovery
You can search by key word, author, title, or subject in DELCAT Discovery. Subjects can be very helpful in focusing a search. The best way to find applicable subjects is to look in the subject headings listed in your results. Below are a few examples of subject headings in entomology and wildlife ecology:
Note that subject headings often have several additional qualifying subject headings, allowing for very specific description of what a title is about.
Be sure to click on the "Holdings" link within the item's record to see if the item is checked out of the library, and to locate the item's call number. For more information about how to locate a book in the library using a call number, please see How To Read A Call Number.
