As you read through your sources, sticky tab the dickens out of passages that might be important for your argument. After you’ve gone through your sources this way, review those particular passages and see if you want to include them in your paper. If so, type them into a separate document reserved entirely for notes, along with a little annotation like “Support for theory x” or “Background for introduction.” Then, all you have to do is organize your notes and--presto!--you already have something very close to a paper outline. Now your job will just be to fit everything together into an argument of your own!
