Many libraries in the United States have instituted interlibrary loan programs, which provide access to materials from all over the country. Patrons can request many different types of materials, including books, CDs, microfilms, audio or video recordings, sheet music, and maps, from both public and private library collections. Materials may be delivered to the requesting library by courier or by mail. In some cases, patrons may be charged a fee to use this service. Fees associated with interlibrary loan programs are generally small and cover only the shipping or delivery costs. 10 In the passage above, the word "interlibrary" means A. for libraries.
