Literature review is an essential predecessor to research, a way of detecting what previous research has yielded, identifying disparities and where to look next. It represents a summary of existing research on a specified topic that compares studies based on design and methods, encapsulates the findings of each, and points out flaws or likely confounding variables that may have been overlooked. Perhaps the most significant criticism of literature reviews is the probability for bias and for unreliable conclusions to be formulated. Taking up a critical perspective, this case study seeks to contribute an account of methodological and theoretical aspects underlying the process of literature examination. The main purpose is to reflect on constituents of the procedures surrounding the topic, by providing a brief case exemplification.
