Making a search plan
When you start doing a research project, you should make a search plan for your information needs. A search plan makes you think about what exactly you are looking for and where you can find it. It helps you to search methodically and efficiently, and to find the best and most relevant information for your purposes.
From this literature you can choose a key publication as starting point to search for additional information using the snowball method and citation searching.
Bear in mind that searching for literature is an iterative process with “trial and error”.
