Annotations in Content

Annotations can be used to provide reminders, help a reader engage with the text, or to add context or further clarification. Highlighting or underlining key words or major ideas is the most common way of annotating in content and makes it easy to find those important passages again. You can go beyond marking up text and write notes on your reaction to the content or on its connection with other works or ideas. You may also find annotations in some texts written by the authors themselves, regarding related topics or expanding on an idea.

  • Notes from the coroner on an autopsy report
  • Notes in a law book showing related court cases
