Tips for writing a literature review
From Diptak Bhattacharya, researcher
Writing a literature review paper offers a unique opportunity to critically analyze and organize current literature. If you’re a graduate student, this will help you understand your field before you start writing your own research.
Here are some suggestions for how to turn this journey into a grand adventure.
Simplify the literature – present the broad picture to the reader
There is a vast array of scientific literature available and it sometimes feels overwhelming to study it systematically. As an author of a review paper, present the literature in an organized way so that your review acts as a handy ‘guidebook’ of the literature. Developing schematic maps and classifications can help the reader visualize the chronology of developments in a field, and also locate particular papers of interest.
Develop an interesting storyline to engage the reader
A review paper should have a strong plot. Introduce the topic using an interesting problem statement that plants a seed of suspense in the reader’s mind. Then, take the reader on a journey that slowly unfolds the origin of the stated problem. Always explain the theory right from the basics. Illustrate concepts through graphics alongside text. Schematic charts and diagrams help demonstrate theories that are complicated to interpret from texts alone, therefore you can use them to keep the reader engaged and help them grasp the theory.
Critically analyze the literature
As a scientific person, it is imperative to assimilate data from different research, and understand its broader implications. Often, you discover hidden scientific trails only through comparing and contrasting research. These trends are not obvious from any stand-alone investigation. An effective literature review paper identifies and interprets these subtle trends and builds ideas and hypotheses for future research in the field.
Be confident to highlight gaps in the literature
A literature review is not merely an exercise to summarize published research, because every research is different and the findings and interpretations may vary. Rather, a review paper is an excellent place to identify the gaps or inconsistencies in the literature. Therefore, you should aim to write a review that leaves a clear impression of what is ‘well understood’, and what still remains a ‘mystery’ to be solved.
