Literature reviews are an integral part of the process and communication of scientific research. Whilst systematic reviews have become regarded as the highest standard of evidence synthesis, many literature reviews fall short of these standards and may end up presenting biased or incorrect conclusions. In this post, Neal Haddaway highlights 8 common problems with literature review methods, provides examples for each and provides practical solutions for ways to mitigate them. However, there is a fundamental difference between brief, narrative approaches to summarising a selection of studies and attempting to reliably and comprehensively summarise an evidence base to support decision-making in policy and practice. Systematic review has become the highest standard of evidence synthesis and is well established in the pipeline from research to practice in the field of health.

Eight common problems with science literature reviews and how to fix them
Metrics details. Systematic literature searching is recognised as a critical component of the systematic review process. It involves a systematic search for studies and aims for a transparent report of study identification, leaving readers clear about what was done to identify studies, and how the findings of the review are situated in the relevant evidence. Information specialists and review teams appear to work from a shared and tacit model of the literature search process. How this tacit model has developed and evolved is unclear, and it has not been explicitly examined before. The purpose of this review is to determine if a shared model of the literature searching process can be detected across systematic review guidance documents and, if so, how this process is reported in the guidance and supported by published studies.
Environmental concerns in the knowledge industry: literature review
Literature reviews can be stand-alone documents, or they can form part of a research proposal or project. A stand-alone literature review aims to summarise and evaluate the current knowledge of a specific topic, whereas a literature review that forms part of a research proposal or project also describes the gaps in the current knowledge that the project aims to address. This module is intended as an introductory guide to writing stand-alone literature reviews.
