Use the Online Catalog to find books. In the Online Catalog you can search for books by subject, or 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.
The UIUC Library is one of 70+ member libraries comprising the I-Share consortium. I-Share libraries share an online catalog, I-Share, and UIUC students, staff, and faculty can borrow directly from the other libraries in the consortium by placing a request through the catalog.
Why bother with subject headings when one can do keyword searches in the Online Catalog?
It’s true that you can find sources on a topic by doing keyword searches. But if you limit yourself to 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 can probably find what you need by doing keyword searches, but if you are doing historical research, 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.
As a rule of thumb, use fairly broad headings, as well as the specific ones that describe your topic, in order to make sure you haven't inadvertently eliminated relevant material that is contained within works of larger scope. Most likely you will find multiple headings to describe your topic, and you should use all of them. 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.
A lot of social history is shelved in the 300s, even when it deal primarily with a single nation or region.
