Library Services

Step 1: Differentiate between core and enhanced services. A library's services can be divided into core (basic, essential) functions and enhanced (value-added) functions.

Step 2: Analyze the options. Circulation, standard reports, and data exchange are all considered standard, core features of a modern library or library management system. Multilingual Support, which allows users to interact with the catalog and services in different languages, is an advanced feature that enhances accessibility and user experience, thus qualifying as an enhanced service.
