The best way to find books at Swem is through the library catalog. When searching for books, only search a few keywords at a time, usually 2 or 3. Do not overwhelm the system with too many search terms at once.
If you don't find what you need at Swem, check WorldCat to see if books of interest are held at other libraries.
If you find a book, order it (at no charge!) through Interlibrary Loan (ILL)
