An Integrated Library System (ILS) includes which of the following components?

An Integrated Library System (ILS) is designed to manage multiple facets of library operations, and the correct answer encompasses several essential components that support the overall functioning of a library.

Specifically, the ILS typically includes acquisitions, which involves the processes related to the procurement of library materials; circulation, which manages the borrowing and returning of these materials; cataloging, which refers to the organization and classification of items in the library for ease of access; and the Online Public Access Catalog (OPAC), which allows patrons to search for and locate materials within the library’s collection.

By integrating these functions into one system, an ILS streamlines library management, enhances the user experience, and fosters more efficient operations, enabling librarians to provide better services to their patrons. In contrast, the other options reference components that either do not encompass the core functionalities of an ILS or focus on isolated aspects of library management without addressing the integration of essential library services.
