Subject Librarians - for help with devising a search strategy for your review; retrieving publications; referencing.
Library Study Skills team - for help with academic writing, planning and structuring your work.
Library Research Support team - for help with deciding where and how to publish your review.
Academic research is not done in isolation, it connects with the work and ideas of others, creating an ever-changing network of knowledge and exploration. Research is often recorded in the literature – formal academic publications such as books or journals, or less formal “grey literature” such as conference papers, theses and reports. Before starting their research, academics will search for, read and review the existing literature to see what has already been published on their topic so that they can position their own work in the existing research landscape, taking into account the work that has been done by others before.
The term literature review can describe a product or a process. As a product, the literature review is part of an essay, report or publication where the researcher summarises and reports on the literature they have read relating it to their own research question, setting the context for their work. As a process, the literature review involves a methodology or series of steps that a researcher will undertake to enable them to identify, appraise and summarise the relevant publications and studies relating to their topic.
