Use the Library Catalog to identify books, journals (but not journal articles), microform collections, and digital collections owned by the University of Illinois. The Library Catalog is the primary tool for exploring the collections of the University of Illinois Library, the second largest academic library collection in the United States. In the Library Catalog you can search for books by subject, and you identify the location within the Library of a particular book or journal. Books and journals are organized in the library by subject. Each item is assigned one or more subject headings and a unique call number. Subject headings are standardized terms from the Library of Congress. The call number is based on the Dewey Decimal Classification or Library of Congress Classification. Boolean operators must be capitalized if used: AND, OR, NOT. Interface automatically truncates some search terms unless Boolean operators are used within the same query line. You can also browse catalog records by call number, creating a "virtual shelf browsing" experience.
