Final answer:
Interlibrary loans allow you to access sources that are not available in your own library's collection.
Step-by-step explanation:
A reason why you should make an interlibrary loan request for a book or article is because your own library may not have access to the specific source you need. Interlibrary loans allow you to borrow materials from other libraries through a networked system. This is especially useful for accessing rare or specialized materials that may not be available in your own library's collection.
Interlibrary loan (ILL) is the cooperative arrangement among libraries that allows books and other materials from one library to be loaned out to a patron from another library. Document delivery is the provision of published or unpublished documents, generally electronically and sometimes for a fee.
The purpose of interlibrary loan as defined by this code is to obtain, upon request of a library user, material not available in the user's local library.
When the library does not have a book or an article that you need, you may request it via interlibrary loan (ILL). Or, on the library's website: Along the top of the library's website, select RESOURCES. In the expanded menu, look under LIBRARY for the Interlibrary Loan link and click it.
