Which feature of e-books makes them particularly suitable for reference works and textbooks?

Internal hyperlinks are a key feature that makes e-books especially effective for reference works and textbooks. These hyperlinks enable users to quickly navigate between different sections, chapters, or related topics without the need to flip through physical pages. This interconnectedness allows for efficient cross-referencing, which is particularly valuable in educational materials where the reader may need to consult various sources or related information simultaneously.

In the context of textbooks and reference materials, this functionality supports enhanced learning experiences by allowing students to easily access definitions, explanations, or related concepts, thereby improving comprehension and retention. The ability to click on links also reinforces the active engagement that digital content can foster, making it easier for users to find relevant information swiftly and seamlessly.

While other features of e-books, such as offline access and audio narrations, can be beneficial, they do not specifically enhance the navigational and reference capabilities that are crucial for academic and professional use. Being more expensive does not contribute positively to the usability or effectiveness of e-books in educational settings.
