To locate key publications relevant to your research topic you will need to invest in advanced search planning.
What is the research problem(s) you would like to address?
Subject areas? Do you need to include databases that are multidisciplinary or even from disciplines such as allied health, law or business?
What kinds of literature do you anticipate as useful in your study?
Where will you find it? Identify appropriate databases with the help of a relevant library subject guide
Do you think it is easy to find these? What do you know about the articulation of the problem within the research community? Are concepts clearly formulated or somewhat difficult to find when that is not the case?
Note: Searching in the early stages are often iterative, not linear, sometimes you will go to unexpected places
