So, this is forward citation tracing that helps you to identify which articles are very influential and which are highly cited in the literature and therefore likely to contain information that scholars have found useful to cite or read. A good idea not to overwhelm you with information overload would be that, you select the last few years of publications and continue with forward citation link search to identify at most four or five articles that will likely to contain the information that you'd like to focus. Your next thing would be to conduct a backward search of the citations. For this, you review an article (either the seminal article that set you to the path of search or an article that looks highly cited and see which other articles did this article cite. Then read a few of the articles in the reference list of that article and gradually using this process, you start developing a sense of which concepts or conclusions, or arguments are worth chasing and pointing to, which we will turn next.
