What is a primary characteristic of interlibrary loan networks?

A primary characteristic of interlibrary loan networks is that they expand access to resources. Interlibrary loan systems allow libraries to lend their collections to each other, thereby significantly increasing the range of materials available to patrons beyond the confines of a single library’s holdings. This collaborative borrowing system enables users to access books, articles, and other resources that may not be present in their local library, fostering a more extensive research capacity and encouraging resource sharing among libraries.

As for the context around the other options, while it might be true that interlibrary loan networks can lead to efficiency in resource use, they do not necessarily reduce the need for library funding, as each participating library still incurs costs. Limiting the number of loans contradicts the very purpose of an interlibrary loan system, which is to facilitate access rather than impose restrictions. Additionally, these networks are designed to serve a broader community, not just local patrons, as they connect libraries across regions, which further emphasizes the expansion of access to resources.
