Work to understand all of the different viewpoints and schools of thought on your topic. This can be done by reading a variety of articles, reading a book or article that gives an overview of the topic and incorporates different points of view, or talking to an expert who can explain the topic in depth.
If you want to find helpful and reliable sources of information, the library is literally the best place to look around. There are numerous books, published articles, journals and etc. that you can choose from about your chosen topic.
It might make sense to bookmark resources on your web browser or make a digital bibliography that allows you to link the resources you found. You might prefer a printed list of your resources or you might want to write down all you have learned that is relevant to your project on notecards or sticky notes and organize your research paper on a table or the floor.
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.
It’s important to be engaged in the topic you’re writing about it, but you don’t have to love it. It’s also good to realize that you can use this research writing assignment as an opportunity to learn about something new. You will be somewhat of an expert in the topic by the end of this process, but you don’t have to know everything right now.
