Why is reviewing existing literature crucial before starting research?

Reviewing existing literature before starting research is fundamentally important as it allows researchers to build on what is already known in the field. This process not only enhances the depth and relevance of the new study but also ensures that researchers do not duplicate efforts already made by others. By engaging with previous findings, researchers can identify gaps in the literature that their work could address, thus contributing to the body of knowledge in a meaningful way.

Moreover, this review helps researchers refine their research questions, theoretical frameworks, and methodologies based on previous studies' insights and outcomes. By understanding the landscape of existing research, scholars can also better position their work within that context, allowing for a more significant impact on practice and policy in social work.
