Annotation (also called mark-up) can be physical or digital. It's any underlining, notes, highlighting or other symbols you make on a page.
If you're using a library's print copy, respect the next reader by NOT marking up the text. Instead, you can photocopy or scan pages to add to your class notes as needed.
Pay attention to the author's claim. Differentiating between the claim and the topic is especially important. What is the author's purpose or intent in writing about the topic? Are they narrating a story, or categorizing branches of knowledge?
What is a claim?
It is an arguable, but plausible, opinion on a topic. It's the result of a targeted research question. Ideally, the claim will be specific and narrow enough for the space allotted in the book or journal.
Track how the claim is developed across paragraphs.
Write a word or phrase next to each paragraph to remind you of the main idea.

The authors (Zoe Bennett, Carol Reekie, and Esther Shreeve) also encourage students to think about the role reflection plays in your academic work. Contemplative practices like prayer, meditation, art-making, journaling, or even talking to yourself can play a powerful role in how you retain and use information from classes and readings.
