A dissertation literature review is a critical summary and analysis of existing research relevant to your topic. It helps define the context of your study, highlight research gaps, and justify your approach. Start by clearly defining your research question, then search for credible academic sources—books, peer-reviewed journals, and reports. Organize the literature thematically or chronologically to show trends, debates, and progress over time. Critically evaluate each source rather than just summarizing it. Focus on how each work contributes to or challenges your understanding. If you're pressed for time or unsure where to begin, dissertation writing services Canada can offer expert help in structuring and writing your review. Finally, ensure your review is well-referenced and aligns with your dissertation's overall argument. Keep your tone objective, your points focused, and your writing concise. A strong literature review lays the foundation for a compelling, research-driven dissertation.
