Taking notes on your reading is a crucial part of research. Taking notes not only helps you remember and find information later; deciding what to record and putting it in your own words will help you understand and think critically about what you read.
While it would be nice if there was one source to rule them all, all the information you need for your research project is rarely found in one place.

You will need a variety of sources from a variety of disciplines by a variety of authors. Think about your information needs:
Once you can answer the questions above, plan your searches.
You may discover that there is no information on your topic or, at least not the information you were looking for. That doesn't mean you have to completely change your topic. Instead of setting aside all that work and starting over, pivot your topic to something you have found information on or break up your topic into separate searches.
For example, if your topic is Birdo from the Mario franchise as one of the first transgender characters in a video game, searching for "Birdo" or even "Birdo Mario" in Library Search, won't return any relevant results. However, searching for "transgender video game" returns results about transgender representation in video games, how transgender gamers interact with video games, and the ethics of game development. Searching separately for "Mario video game" will return results about the Mario franchise and gaming history. Though there were no results specifically about Birdo as a transgender character in Library Search, results from the two separate searches provide enough relevant material.
