Research is NOT a simple, linear timeline: first you have a question, then you find sources, then you write a paper, and you're done.
Rather, it is like a cycle or spiral in which your ideas evolve by repeatedly searching, reading and creating information. You can expect to need to find more information throughout your research project for several reasons:
The best search strategies use multiple methods to find information. This lets you adjust to the setbacks that are a normal part of learning. You can simply switch over to a different strategy and start anew. That may be all you need to turn up a key source that unlocks your research for you.
In the following sections, we'll learn about six different strategies for finding information: through keyword searching, subject searching, browsing, looking up citations, reading reviews, and asking people for help.
Many of us are used to finding information through Internet search engines.
Web searching through Google and DuckDuckGo is effective when you already know what you're looking for and the answer to your question is something specific, such as the hours a store is open or the Wikipedia page on a person.
They aren't as effective when you don't know what you're looking for and the answer is a matter of interpretation. Of course, that is the essence of research - learning something new (to you) and making sense of multiple perspectives.
Library search tools such as catalogs and databases have been designed around the needs of scholars. These specialized search tools make it easy to discover information and determine whether it is relevant, even if you don't know the right words to search on.
