The best means of searching for materials not in Ottenheimer Library is WorldCat - also known as OCLC. It provides information on worldwide library holdings of books, periodicals, theses, dissertations, media, and other material. If you know of a book you need that Ottenheimer Library does not own, you can search it here to see which other libraries have copies. In many cases, our Interlibrary Loan department can obtain the book for you from another library.
