Annotations are notes or comments added to a text, image, or other content to provide additional information or context. They can help clarify complex ideas, highlight important points, or offer personal insights. Annotations are commonly used in academic settings, where students may annotate books or articles to enhance their understanding of the material. In digital formats, annotations can be made using various tools and software, allowing users to highlight text, add comments, or link to related resources. This practice is beneficial for collaboration, as it enables multiple users to share their thoughts and feedback on a document or project, fostering a deeper discussion around the content.
