Before you start a literature search it's important to plan what steps you will take. Ask yourself:
Where is the best place to find information for your topic?
What are the limits of your search?
Are there any research models you can use?
You may also want to refer to our Libguide on Systematic Reviews: finding and managing the evidence for more advanced searching strategies.
It is important that you plan your search in a methodical way to find the most relevant sources of information. If you can, turn your search topic into a research question. This will help you to formulate a specific and targetted search. For example, the topic 'thromobolytic therapy and heart attack' is quite vague. Instead, it could be phrased as:
How does thrombolytic therapy in A&E improve outcomes for heart attack patients?
From here, you can identify the key concepts in your search and come up with some alternative terms and keywords to search. Use the example table below as a guide. You might want to create your own table in a word document or on a piece of paper.
Write out your essay topic as a question:
|How does thrombolytic therapy in A&E improve outcomes for heart attack patients?|
Identify the important concepts in your questions and list any alternative terms underneath:
clot busting drugs
accident and emergency
Searching alternative terms will help you to find more results. Remember that searching is an iterative process and you may want to add or delete search terms after reviewing your results.
As well as using keywords, you can also search for your concepts as subject headings/terms which the video below explains in more detail.
There are many specialist healthcare databases that you may want to use to implement a literature search. They can all be found on the A-Z Databases page, but key databases include:
