Explain the difference between book materials and non-book materials, and give examples of each.

### Why this is right The distinction is mainly the format in which information is provided. Book materials are printed resources that readers use by reading text or viewing printed pages, while non-book materials present information in another form, such as digital text, sound, or images. Both types are selected to meet readers’ information or teaching needs. ### The concept **Book materials** are resources printed on paper, including textbooks, reference works such as encyclopedias, and periodicals, which are publications issued regularly, such as magazines and journals. The term includes printed publications beyond books with covers. **Non-book materials** are resources that are not printed publications: electronic resources are accessed on digital devices, audiovisual materials use sound, moving images, or both, and visual aids communicate through images or other visual displays. The format, rather than the subject or purpose, determines the category. For example, a printed textbook is book material, while the same text in a digital file is non-book material. | Type | Format | Examples | |---|---|---| | Book materials | Printed pages | Textbooks, encyclopedias, magazines | | Non-book materials | Digital, sound, or visual formats | Electronic resources, videos, maps, charts | ### What a good answer covers - Book materials are print resources. - Examples include textbooks, reference works, and periodicals. - Non-book materials are non-print resources. - Examples include electronic resources, audiovisual materials, and visual aids. - Both kinds are acquired to meet information or instructional needs. ### Terms - **Reference work**: A resource designed for looking up information on particular topics, rather than usually being read from beginning to end. - **Periodical**: A publication released in separate issues at regular intervals, such as a magazine or journal. - **Electronic resource**: Information stored or provided in digital form and accessed using an electronic device. - **Audiovisual material**: Material that uses sound, moving images, or both to present information. - **Visual aid**: An image or display, such as a chart or map, used to explain or support information. ### Remember Classify a resource by its format: printed pages are book materials, while digital, sound-based, or visual formats are non-book materials.
