In library and information science, the physical and digital items acquired, organized, and preserved by a library to fulfill the information needs of its users are collectively referred to as:

### Why this is right A library’s **resources** are the materials it provides to meet users’ information needs. Because the question includes both physical and digital items that the library acquires, organizes, and preserves, it describes the library’s collection of resources. ### The concept **Library resources** include materials such as books, journals, maps, audio recordings, and digital files or databases. A library selects and acquires these materials, organizes them so people can find them, and preserves them for use over time. **Circulation** is the process of lending and returning materials. **Classification** groups materials by subject or another system, while **cataloging** creates descriptive records that help users identify and locate them. | Term | What it refers to | |---|---| | Library resources | Materials the library provides to users | | Library circulation | Lending and return of materials | | Library classification | Grouping materials into an organized scheme | | Library cataloging | Creating records that describe and help locate materials | ### The other options - **B. Library circulation**: This refers to lending and returning library materials, not the materials themselves. It is tempting because circulation is a service users commonly associate with books. - **C. Library classification**: This is the system for grouping materials, often by subject, so related items can be found together. It describes an organizing method, not the items being organized. - **D. Library cataloging**: This is the process of making records that describe materials and help users find them. It describes how resources are represented in a catalog, not the resources themselves. ### Terms - **Digital**: Stored or accessed electronically, such as an online journal or an electronic book. - **Cataloging**: Creating descriptive records for library materials so they can be identified and located. - **Classification**: Arranging materials into groups, often by subject. - **Circulation**: The library process for lending and returning materials. ### Remember If the question asks what the library’s physical and digital materials are called, choose **library resources**; circulation, classification, and cataloging describe activities or systems related to those materials.
