Once you’ve gathered all your research, print it out (if it is an online source) and gather post-its or anything you need to mark notes in the books/magazines you are using. This step is very important: read through your research, take notes on what you think is important, and highlight key facts and phrases. Write directly on copies you’ve made, or use slips of paper tucked into pages to mark places of importance.
Any information that doesn’t fit within the framework of your outline, and doesn’t directly support your thesis statement, no matter how interesting, doesn’t belong in your research paper. Keep your focus narrow and avoid the kitchen sink approach. (You know, the one where you throw in every bit of interesting research you uncovered, including the fungal growth in the U-joint of your kitchen sink?) Everything you learn may be fascinating, but not all of it is going to be relevant to your paper.
An analytic research paper offers a fresh look at an important issue. The subject may not be controversial, but you must attempt to persuade your audience that your ideas have merit. This is not simply a regurgitation of ideas from your research, but an offering of your own unique ideas based on what you have learned through research.
Take a trip to your local library or university library. Although it may seem old fashioned, libraries are chock full of helpful research materials from books to newspapers and magazines to journals. Don’t be afraid to ask the librarian for help either - they are trained in research and know where everything about your topic is located.
