Literature searching is a structured and organised way of finding information on a topic, most often using online resources such as NUsearch [UK, China, Malaysia] and subject databases.
Before you start searching, be clear about what it is you're looking for. Think about keywords you could use and be prepared to refine or broaden your search depending on your results. You may have to try your search more than once before you find what you're looking for.
Developing your search skills will enable you to get the most out of online searching and can help you to:
- Build a focused search to find relevant information on a topic
- Explore different aspects of a topic
- Search more efficiently and save time
Planning your search and identifying keywords
It's easy to become overwhelmed by the amount of information available. Planning your search in advance will enable you to quickly and easily find relevant information and save you time in the long run.
The first step is to think about your topic and identify keywords to describe it. Keywords allow you to be specific about the topic you're interested in and to modify your search to find more relevant results.
The following video Search skills: thinking about keywords shows you how to break down your topic into key concepts and consider alternative keywords and spellings.
Alternatively, go to Thinking about keywords (pdf).
You can apply a range of search techniques to help you find relevant information online. Use the following tutorials for some hints and tips.
