Systematic Literature Reviews (SLRs) have increased in popularity in the social sciences as a methodological research technique, adapted from the very prescriptive reviews used in health disciplines. Systematic searching forms part of the systematic review but is not the sole research method. A Systematic Literature Review is the research methodology in itself and may be the final product.
While literature searches may only require one database or search, systematic searches require a more thorough and comprehensive approach. Multiple databases must be searched using a developed search strategy. They aim to discover all the research on a topic, identify any gaps in the research and to produce more reliable findings that can be used to inform decision making.
Searches used for systematic reviews require more planning and preparation compared with simple searching to ensure that they are comprehensive and rigorous. They need to be focused with a clearly defined research question, transparent and recorded so that they are replicable and updateable.
