Do a keyword search to lead you to the Library of Congress Subject Headings used for your topic. Using these headings will help you find more items on the same topic, as well as give you the vocabulary for further keyword searching.
1. Browse the list of results from your keyword search. When you find a promising title, click on it to open the full view.
2. Read the table of contents and summary, if available, as well as the subject headings, to help gauge the item's relevancy.
3. Click on any of the subject headings to find all the items in the library catalog that have that subject heading assigned.
4. Alternatively, use the subject terms you now know in a new search in combination with your keywords or with other subject terms.
5. Browse the lead term (also called the "main heading") of the subject heading to see what other subtopics that subject has by using the "Subject begins with" choice in the drop-down menu of the "Basic" search. For example, for the subject heading "Women--United States--Identity," browse "Women United States" as a "Subject begins with" search to see other subtopics (called "subheadings") of "Women--United States."

an exact author match [last name, first name], such as Larsson, Stieg
