Final answer:
If a book isn't available at your library, you can use interlibrary loans, search the library's online catalog, or consult with a librarian for alternative digital resources or interlibrary loan options.
Step-by-step explanation:
If you are looking for a book that is not available in your library, the text recommends that you typically can get the source through a networked system called interlibrary loans. By using this service, your library borrows the book for you, providing guidance on the format of the materials and how long you will have access to them. In addition, you can also consult your library's online catalog, look for additional resources on the internet, or ask a librarian at your college for assistance, who might be able to request it through Inter-library Loan (ILL) or direct you to other digital databases or resources for your research.
