To find books in the Library, begin with the Library Catalog:
If you can't find your book in our Library Catalog, you should next check to see if it's available from an I-Share Library. To search all I-Share Libraries, switch to "Advanced Search" in our library's catalog, and select the "All I-Share Libraries" radio button.
After you have explored the books available to you here at the University of Illinois, and also at other I-Share libraries, you will want to expand your search using WorldCat:
If you find a book in WorldCat that you would like to use for your research, you can request it through Interlibrary Loan:
Subject headings are used to collocate records for works on a common subject under a single, standardized heading.
The subject headings used in the Library Catalog are standardized Library of Congress terms, which may be “subdivided” (made more specific) by geographic area, chronological period, genre, or sub-topic. The language of subject headings is not at all intuitive or natural, so you shouldn’t hesitate to ask a librarian for help in finding the correct subject headings.
A good way to identify subject headings for a topic is to do a keyword search in the Library Catalog using terms you think describe the topic, in order 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.
In addition to the 14 million+ printed books available to you here in the Library, we have several important digitized book collections. Listed here are primarily those ebook collections that you would likely use to find secondary sources; books, of course, can also be primary sources and the collections most likely to contain books as primary sources are listed on the page for Primary Sources.
Ebooks (or digitized books) can also be discovered using the Library Catalog (see above).
