What types of things should you note, when reading? Consider:
Create a vocabulary list at the front or back of your text that includes new terminology, interesting concept words, etc.
Direct quotes can be underlined within your own text or recorded on stickies or index cards.
Write brief summaries or a paraphrase of information found. In your own copy, you can place this at the beginning or end of each chapter or section. If the resource is not yours, keep this information in a notebook or on a notecard.
Your own ideas about the text (expanded information or questions). In your own copy, you can write these in the margins of the page, near the referenced passage. If the copy belongs to someone else, use stickies or index cards placed bookmark fashion between the appropriate pages.
When you read longer texts, keep a list of key information with page references. On your own copy, this might be recorded the inside cover of the book, or perhaps on the back page of a scholarly article. If the resource is not your own, keep this information in a notebook or on a notecard.
