The UIUC Library is one of 70+ member libraries comprising the I-Share consortium. I-Share libraries share an online catalog, Illinet Online, and UIUC students, staff, and faculty can borrow directly from the other libraries in the consortium by placing a request through the catalog.
Use the online catalog to do a subject search for books or to find out where a particular book or journal is located in the Library.
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.
It’s true that you can find sources on a topic by doing keyword searches. But if you only do keyword searching, you are likely to miss important material on your topic that uses other terms. If you only need two or three books, you'll probably find what you need by doing keyword searches, but if you are doing a research paper, you can’t afford to miss critical material on your topic. For a comprehensive subject search, search with subject headings as well as keywords.
A good way to identify subject headings for a topic is to do a keyword search in the online catalog using terms you think describe the topic and try to identify a few relevant books. Look at the full record for those books to see what subject headings were used, then do another search on those headings.
You will probably find more than one subject heading to describe your topic. In order to see records for all the books on the topic, use all of the subject headings you find. Even if you find the perfect subject heading describing your topic, you'll need to use broader headings as well, in order to make sure you don't eliminate relevant material that is contained within works of wider scope.
You can narrow your search in the online catalog by combining subject headings (as a phrase) with keywords, using the “Advanced Search” option.

To search the online catalog, go to the Library Gateway and click on Library Catalog. The online catalog offers both “Quick Search” and “Advanced Search” options. Use “Advanced Search” to identify subject headings on your topic, to combine subject headings (or elements from subject headings) in a Boolean search, or to combine keywords from any part of the record with subject headings to narrow your search.
Use “Quick Search” to browse a subject heading, to search a title when you know exactly how it begins, to locate a work or works by a particular author, or to search by call number for a specific book.
