Dear incoming rat,
The best ways to handle secondary sources in the ERH 101-03 is when paraphrasing, the best thing to do is to read the info two or three times and then put it away and write the paper using the memory you have to avoid coping the info and the work being considered plagiarized. Including the source is extremely important and will demonstrate that you have not plagiarized. When quoting it is important to only quote when the original text is perfect and that the quote is not changed in the essay. A citation is always needed. Another important aspect about using quotes is that they can never be bombed in; they have to include words ether before or after to introduce the quote and set it up for evaluation.
