From Picking Your Topic IS Research [Video], by the North Carolina State University Library, 2013, YouTube (https://youtu.be/Q0B3Gjlu-1o).
Make sure you pick a topic with a manageable scope, neither too broad, nor too narrow.
As you start searching for information on your topic, you will fine-tune and tweak it based on the information you find. Starting your research early will help you determine if your topic is too narrow or too broad. You may find an article that really interests you and pulls you in that direction. Keep an open mind as you start your research.
Not finding enough information?
Having a narrow topic is one reason you will not find enough information. There are other reasons as well.
Have a back-up topic in mind. Sometimes your first topic is not the right one, for various reasons. It’s a good idea to have a back-up topic in mind in case the first one does not work out.
