Electronic resources, visual aids, media resources etc are ______

### Why this is right Libraries classify materials by their format as well as by their purpose. Electronic resources, visual aids and media resources are formats other than ordinary printed books, so they fit the broad category **non-book materials**. ### The concept **Non-book materials** are library resources that are not conventional printed books. They may include electronic resources, such as digital files, and media resources, such as audio or video recordings. Visual aids, such as charts or slides, also belong in this broad category. The label describes the material’s format, not what it is used for or who owns it. | Category | What it describes | |---|---| | Non-book materials | Format: resources other than conventional books | | Reference material | Purpose: resources consulted for information | | Electronic material | Format: resources stored or accessed electronically | | Library property | Ownership: items belonging to the library | ### The other options - **A. reference material**: describes resources used to look up information, such as dictionaries; it is about purpose, not format. - **B. library property**: describes who owns an item. Books and non-book materials can both be library property. - **C. electronic material**: describes only electronically stored or accessed resources. It is tempting because electronic resources fit this label, but visual aids and other media resources may not be electronic. ### Terms - **Non-book materials**: Library resources in formats other than conventional printed books. - **Visual aids**: Materials, such as charts or slides, used to help communicate or explain information. - **Media resources**: Materials such as audio or video recordings, used to provide information or entertainment. - **Reference material**: A resource intended for consultation to find specific information. - **Electronic material**: A resource stored or accessed in electronic form. ### Remember A category based on format answers “What kind of material is it?”: resources that are not conventional books are non-book materials.
