Interlibrary loans are a service that allows library patrons to borrow books and other materials from libraries outside their own. If a local library does not have a specific item, they can request it from another library, expanding access to a wider range of resources. This service is beneficial for finding rare or specialized items that may not be available locally. The process typically involves filling out a request form at the local library, which then communicates with the lending library. Once the item is received, patrons can check it out just like any other library material, often for a limited time.
