Once you have found material you need to make sure you don’t lose it!
Unfortunately, there isn’t a “best” way to get yourself organized and there’s not just one single answer. The bottom line is you have to choose a system that works for your learning style and your writing habits.
Research with your final product in mind. As you research, think about what “subheadings” or chunks you may want to write about (even though you don’t have all your information yet).
Keep a journal/Write a research plan.
