When writing your outline, keep your destination in mind. The outline should have the thesis statement placed at the top of the page where it can be referred to often. Your teacher can help guide you through the outlining process. Keep in mind, the outline is not meant to hamper or restrict you, but can be changed and revised to allow you to better prove your thesis. There are many ways in which to take notes.
Some people prefer index cards.
The identification of source is particularly important in your attempts to avoid plagiarism. Remember, the better the note taking, the better your paper. Summary notes take more time and effort, but they save time in the long run, since they can be incorporated, verbatim, into your final paper. When taking summary notes, read your source at least once, digest it, look away from the source, write the summary in your own words, and then check it again for accuracy. Ask your teacher for help if you are experiencing difficulties taking notes.
