LIterature Review vs. Systematic Review
Literature review is a comprehensive summary of previous research on a topic. Literature review may be included as part of a research article; or an entire article may be literature review of previously published research. Such articles typically include "review" or "survey" in the title.
This article provides a good overview of a literature review process applicable across disciplines.
Systematic (literature) review is an in-depth, structured literature review designed to answer a specific question. It originated in healthcare and medical evidence-based practice, but systematic reviews have been gaining popularity in other disciplines, including computer science.
Systematic reviews summarize and evaluate the research on a specific topic:
- Identify relations, contradictions, gaps, and inconsistencies
- Compare studies in terms of assumptions about the research question, experimental method, data analysis, and any conclusions drawn
- Inform areas of future research and practice

Systematic Review Steps
-
Formulate clearly defined question
- Find existing reviews of your topic/domain to identify gaps and avoid repetition of previous work. You may add review, survey, "systematic review" to your topic search
- Example: What current research techniques have emerged in regards to IoT applications and approaches in the last decade?
-
Develop keywords
- Example: digital forensic investigations of internet of things applications
- Example search: (application* OR software* OR “app” OR “apps”) AND (iot OR “internet of things”) AND (forensic* OR investigat* OR crime* OR criminal*)
- Identify appropriate databases
- Determine other inclusion/exclusion criteria
- Include items based on date range, methods, topic, access, etc.
- Exclude items based on language, study type (reviews, surveys, or non-peer-reviewed), or topic
-
Run searches
- Modify search to fit database
- Export results to a citation manager like EndNote or Zotero
- Combine results using a tool like Rayyan
- Deduplicate
- Select studies for inclusion based on pre-defined criteria
- First by title/abstract then full text (ctrl/cmnd+f is your friend)
- Evaluate bias
- Present and summarize findings
- Including detailed search methods and selection criteria
REMINDER: You may find examples of systematic review and literature review articles on Getting Started page.
PRISMA 2020: Guidelines and Checklist for Systematic Reviews
- The PRISMA 2020 Statement: an Updated Guideline for Reporting Systematic ReviewsThe Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement, updated in 2020, provides guidance for authors. It includes a 27-item checklist, an expanded checklist with reporting recommendations for each item, the PRISMA 2020 abstract checklist, and revised flow diagrams for original and updated reviews.
Originally developed for healthcare fields, these guidelines are now adopted by other disciplines.
