A research paper is a large scientific work assigned to students of higher levels of schools, as well as in colleges and universities all over the world. The main goal of this project, regardless of the subject for which it was assigned, is to define a particular issue, research it, and provide new ways to solve it that can be used for further investigation of the problem.
If you find one really awesome book or journal that fits your topic perfectly, try looking in the works cited/bibliography/reference list at the end of it. This should contain many more books and journals that are about your topic as well.
Whenever possible, choose a topic that you feel passionate about. Writing about something you enjoy certainly shows in the final product, making it more likely that you will be successful writing a paper about something you enjoy.
Although you may be limited by specific classroom or work related guidelines, choosing your topic is the first and most important step in your research paper project. Regardless of whether your topic can be anything you want or has rigid requirements, it is important to keep a few questions in mind: Is there enough research available on this topic? Is the topic new and unique enough that I can offer fresh opinions? Is it pertinent to my class/occupation?
