Annotation Marks That Actually Help

Develop a small, consistent annotation system that records thinking instead of just highlighting.

Highlighting feels productive but often records nothing except that a sentence looked important. Effective annotation records a reaction or a function. A compact system might use a few symbols: a box around key terms, an underline for the central claim, a question mark for confusion, an exclamation point for surprise, and brief margin notes such as 'evidence,' 'counter,' or 'shift. ' The margin note is what matters most, because it forces you to name what the passage is doing.

Imagine a paragraph that begins 'Some historians argue the canal was built for trade, yet the records suggest otherwise. ' A useful annotation might be: underline 'records suggest otherwise,' and write 'author's claim vs. other view' in the margin. Later, when writing an essay, you can find the author's position in seconds. Limit yourself: if more than a third of a page is marked, the marks stop meaning anything. Annotation slows reading slightly but makes rereading far faster.
