Academic libraries use the Library of Congress classification system to assign call numbers for print materials. The call numbers are assigned based on a book's topic, in theory allowing you to browse the library shelves by subject. Search engines find material based on whether the search terms you've used are present. Browsing can be a way of finding material which uses different terms than the ones you've used or terms and relationships you hadn't thought of yet.
