Manuscript Preparation and Writing Standards2

2. Conducting and Writing the Literature Review

Purpose of the Literature Review

The literature review is one of the most critical components of a scholarly manuscript. Its primary purpose is not merely to summarize previous studies but to critically evaluate, synthesize, and contextualize existing knowledge within a specific research domain. A well-developed literature review demonstrates the author’s familiarity with the current state of research, identifies unresolved questions and knowledge gaps, and establishes a clear rationale for the present investigation.

In high-impact Q1 and Q2 journals, reviewers expect the literature review to provide a coherent intellectual foundation for the study rather than a descriptive list of prior publications.

Objectives of an Effective Literature Review

A rigorous literature review should:

• Present the current state of knowledge in the research field.
• Identify major theoretical frameworks and conceptual models.
• Critically assess previous empirical findings.
• Highlight methodological strengths and limitations of prior studies.
• Identify inconsistencies, controversies, and unresolved issues.
• Reveal theoretical, methodological, or practical research gaps.
• Demonstrate the originality and necessity of the current study.
• Position the research within ongoing scholarly debates.

Characteristics of a High-Quality Literature Review

1. Critical Rather than Descriptive

One of the most common weaknesses in academic manuscripts is the tendency to summarize studies without critical evaluation.

Weak approach:

Smith (2020) studied climate adaptation. Johnson (2021) examined resilience. Brown (2022) investigated sustainability.

Strong approach:

Although previous studies have extensively examined climate adaptation and resilience, findings remain inconsistent regarding the long-term effectiveness of adaptation strategies in vulnerable urban environments. Furthermore, limited attention has been devoted to the interaction between social resilience and environmental governance, indicating an important gap in current knowledge.

High-impact journals favor analytical synthesis over sequential reporting.

2. Logical Organization

The literature review should follow a logical structure rather than a chronological listing of publications.

Common organizational approaches include:

Thematic Structure

Studies are grouped according to themes or research topics.

Example:

• Climate change mitigation
• Climate adaptation
• Urban resilience
• Environmental governance

Methodological Structure

Studies are categorized according to research methods.

Example:

• Quantitative studies
• Qualitative studies
• Mixed-methods studies

Theoretical Structure

Studies are organized according to theoretical perspectives.

Example:

• Ecological modernization theory
• Sustainable development theory
• Social-ecological systems theory

Chronological Structure

This approach may be appropriate when tracing the historical evolution of a concept or field.

Integrating Sources Effectively

Authors should avoid discussing each source independently. Instead, they should integrate multiple studies to build a coherent scholarly narrative.

Example:

Recent investigations have consistently demonstrated the importance of urban green infrastructure in mitigating environmental risks (Author A, 2020; Author B, 2021; Author C, 2023). Nevertheless, significant disagreement remains concerning the long-term economic efficiency of such interventions, particularly in rapidly expanding metropolitan regions.

This approach demonstrates synthesis rather than simple reporting.

Identifying Research Gaps

A high-quality literature review culminates in the identification of a meaningful research gap.

Research gaps may include:

Theoretical Gaps

Existing theories fail to explain a particular phenomenon adequately.

Example:

Current sustainability frameworks provide limited explanations for the interaction between digital technologies and ecosystem resilience.

Methodological Gaps

Previous studies relied heavily on a single methodological approach.

Example:

Most investigations have employed cross-sectional survey designs, while longitudinal evidence remains scarce.

Empirical Gaps

Certain populations, regions, sectors, or contexts remain underexplored.

Example:

Research on climate adaptation has predominantly focused on developed economies, whereas evidence from developing countries remains limited.

Practical Gaps

Existing knowledge has not been translated into practical applications or policy recommendations.

Establishing the Research Rationale

Following the identification of research gaps, authors should explain how their study contributes to advancing knowledge.

Example:

To address these limitations, the present study develops an integrated analytical framework combining environmental, technological, and socio-economic dimensions of sustainability. By applying this framework to urban ecosystems, the study contributes both theoretical insight and practical policy implications.

This transition connects the literature review directly to the research objectives.

Recommended Sources for Q1/Q2 Publications

Authors should prioritize:

• Peer-reviewed journal articles.
• Highly cited foundational studies.
• Recent publications from the last five years.
• International scholarly literature.
• Indexed databases such as:
  • Scopus
  • Web of Science
  • PubMed (where applicable)
  • Dimensions
  • Crossref

Sources that should be used cautiously include:

• Non-peer-reviewed websites.
• Popular media articles.
• Blogs and opinion pieces.
• Unverified online content.

Recommended Citation Balance

Although requirements vary among disciplines, manuscripts submitted to Q1/Q2 journals typically demonstrate:

• Strong engagement with recent literature.
• Appropriate balance between foundational and contemporary sources.
• Extensive use of international references.
• Limited reliance on self-citations.
• Comprehensive coverage of influential studies in the field.

A literature review should not merely demonstrate that sources were consulted; it should demonstrate scholarly mastery of the research landscape.

Common Mistakes in Literature Reviews

Authors should avoid:

Excessive Summarization

Listing studies without analysis or synthesis.

Lack of Critical Evaluation

Accepting previous findings without examining limitations.

Outdated References

Overreliance on older literature while ignoring recent developments.

Poor Organization

Moving randomly between topics without a clear structure.

Citation Inflation

Including numerous references without meaningful discussion.

Missing Research Gap

Failing to explain why the current study is necessary.

Overreliance on Local Literature

Neglecting major international scholarship and global debates.

Checklist for Authors

Before submission, ensure that the literature review:

✓ Defines the current state of knowledge.

✓ Synthesizes rather than summarizes prior studies.

✓ Demonstrates critical analysis.

✓ Incorporates recent and influential literature.

✓ Identifies theoretical, methodological, or empirical gaps.

✓ Establishes the originality of the study.

✓ Leads logically to the research objectives and hypotheses.

✓ Aligns with international standards expected in Q1/Q2 journals.

Editorial Recommendation

For manuscripts intended for publication in high-impact journals, the literature review should be regarded as a scholarly argument rather than a bibliography narrative. Its ultimate function is to convince reviewers and readers that a significant scientific problem remains unresolved and that the present study offers a meaningful contribution toward addressing that problem.
