You have several options when searching the Library's catalog. If you are looking for books by a specific author or if you know the title of a book and want to see if the library has it, then you would either do an author search or a title search. You can also do a periodical title search to see what journals, magazines and newspapers the library has in its collection.
To search for books on a particular topic you have two choices: (1) words or phrase search OR (2) subject search.
(1) A words or phrase search is a keyword search. Every item in the catalog has a record that provides
information about it. A keyword search allows you to search for words
that appear somewhere in a catalog record. The catalog record includes
the title, author(s), publication information, Library of Congress Subject
Headings, and sometimes the table of contents. Doing a keyword search
does not guarantee that all of your results will be about your topic.
It only means that the words you entered appear somewhere in the catalog
records of the items retrieved in your search results.
