In this chapter, we will discuss: why a literature review is needed and what role it plays in academic research; explain how to identify scholarly schools, approaches, and the evolution of a research field; describe how to use academic databases to search for sources; and provide practical advice and examples of prompts on how AI can help in compiling a review.

Why is a literature review necessary?

Any serious academic research begins with a review of existing literature. In the context of international studies, where topics are often complex and interdisciplinary, a high-quality literature review is especially important. Using the dynamically developing field of digital diplomacy as an example, we will examine why a literature review is needed, how to compile it correctly, and what tools can help in this process.
A literature review — an analytical overview of previously published works on a topic that serves as the foundation for your own research.
Digital diplomacy (sometimes referred to as e-diplomacy, net diplomacy, or twiplomacy) is a relatively new field in international relations, associated with the use of digital technologies and social media in diplomatic practice. Since this field has emerged only over the past two decades, it is still in a formative stage: a relatively small number of studies have been published, and a unified theoretical framework is only beginning to take shape. This is precisely why reviewing the existing literature on digital diplomacy is a creative task that requires a systematic approach.
A literature review performs several important functions in academic work. Its main purpose is to demonstrate the current state of knowledge on your topic and thereby justify the niche for your own research.
A literature review is necessary in order to:
Ultimately, the literature review leads the reader to the hypothesis or research questions of your work. After reading the review, it should be clear what conclusions can be drawn from existing knowledge and which questions remain unanswered—these are precisely the questions your research will address.

    A literature review is not simply a list of sources you have read with brief summaries. It should not look like an abstract or a collection of annotations. On the contrary, a good review is a coherent narrative in which sources are compared, contrasted, and grouped by meaning.

ВIt necessarily includes analysis and evaluation: you show your attitude toward other authors' works, highlight strengths and weaknesses, and identify commonalities and contradictions. A literature review is your argument about what is known and unknown on the topic, not merely a report on what you have read.
In summary, a literature review plays the role of both a foundation and a compass: it supports your research with accumulated knowledge and points to the direction in which this knowledge should be expanded. Without a solid literature review, academic work risks being groundless or repeating a path already taken by another researcher.

Organization and grouping of literature

One of the challenging tasks in writing a review is structuring numerous sources in a logical and reader-friendly way. Since even a narrow topic can generate a large body of literature, it is important not to get lost in details but to identify the main lines of discussion. There are several approaches to grouping and organizing literature in a review. Let us consider the main ones and illustrate how they can be applied using digital diplomacy as an example.
/grouping by issues

Thematic approach

The thematic approach means distributing the literature according to subtopics, ideas, or concepts within your research. Key research directions within the problem are identified. For example, when studying digital diplomacy, the literature can be divided into the following conditional groups:
The scheme above is only one option for thematic organization. Your task is to identify the main themes around which sources can be grouped and, within each thematic block, compare the positions of different authors.
/grouping by issues

Conceptual approach

The conceptual (theoretical) approach is close to the thematic one but focuses on theories and paradigms used in research. In this case, review sections are built around different scholarly approaches to the problem. For example, in digital diplomacy one can identify works written from the perspectives of:
If different theoretical approaches are evident in your topic, it is worth structuring the review around them. For example: "The Constructivist Approach to Digital Diplomacy" vs. "The Realist Approach," describing how they differ in interpreting the phenomenon.
/grouping by authors and schools

Personal approach

Another way to structure a review is to group sources by key authors or scholarly schools.
Thus, the personal approach allows you to acknowledge the main contributions of individual researchers and schools of thought. This is especially appropriate if your topic is new and the field is concentrated around a few names, or if you want to emphasize differences in national approaches.
/grouping by methods

Methodological approach

Another dimension of literature analysis is grouping by research methods used. This helps the reader understand what different authors' conclusions are based on and how reliable they are.
For digital diplomacy, the following methodological groups can be identified:
  • Qualitative studies
  • Quantitative studies
  •  Network analysis
  • Big Data
  • Mixed methods
Why this is useful: the reader of the review will understand the robustness of different findings. Qualitative studies provide depth and insights but may be subjective and not always generalizable. Quantitative studies provide scale but may miss nuances. If all studies in a particular subtopic are qualitative and reach similar conclusions, and you find even one quantitative study confirming or challenging them, this is worth noting. In addition, discussing methods lays the groundwork for identifying "gaps."
Example:
"The lack of panel-based quantitative studies does not yet allow for definitive conclusions about causal relationships between the influence of tweets and real diplomatic events"—such a conclusion logically follows from a methodological review of the literature.
/evolution over time

Chronological approach

Chronological structuring presents the literature in the order of the development of ideas over time. This allows you to demonstrate the evolution of views and how the accumulation of knowledge has changed understanding of the topic. For digital diplomacy, as a relatively young field, the following stages can be distinguished:
The chronological approach is best combined with the thematic one: within each theme, move from older works to newer ones. This allows you to summarize how the current understanding has emerged. The key is not to turn the history of development into a dry chronology. Always highlight the meaning of changes.
Example:
"If in the early 2010s the literature focused on the potential of social media, by the end of the decade attention had shifted to analyzing the effectiveness of these tools in practice, and many authors became more skeptical."

Combined approach

In practice, a combination of all the above approaches is often used. For example:
  • first, briefly outline the historical background (chronologically);
  • then organize the main body thematically or conceptually (comparing approaches);
  • within thematic sections, highlight key authors or schools.
There is no universal recipe. The structure of the review should follow the logic of your argument. Sometimes it is appropriate to discuss theories first (conceptually), then move to practical cases (thematically), mentioning who wrote what (authors) and when (chronologically).
If the review is extensive, you can use a multi-level structure with subheadings reflecting a combination of approaches.
Example:
"Social Media and Diplomacy" (theme) as a subheading, with subsections such as "Experience of Major Powers," "Experience of Small States," "Optimistic Assessments" vs. "Critical Perspectives," etc.
  • Tip

    When drafting a review plan, write out all sources on cards with notes on their key arguments. Then try grouping the cards by themes, theories, or chronology. See which grouping most clearly tells the story of the field. Use that as your foundation.

Having clarified the principles of organizing the literature, we now turn to the question of how to practically find and collect this literature. After all, before grouping sources, you need to ensure that all key works have been gathered. This is the subject of the next section.

Searching for literature in academic databases

To compile a high-quality literature review, it is not enough to know how to analyze sources—you must first find and select them. In the era of digital scholarship, most relevant publications are available through online databases and academic search engines. Let us consider the main academic databases useful for international studies and how to use them effectively.
Google Scholar
Scopus
Web of Science
eLibrary

Google Scholar

Google Scholar is probably the most popular starting tool for searching academic literature. It is a free search engine that indexes scholarly articles, books, dissertations, reports, and more.
Advantages of Google Scholar
  • Broad coverage and simplicity
    The interface resembles standard Google: enter keywords and receive thousands of results. Google Scholar searches titles, full texts, and metadata, allowing it to find articles even when the topic is mentioned within the text rather than only in the title.
  • Multilingual search
    If you need sources in Russian, enter the query in Russian. Google Scholar will find Russian-language articles as well as their translations or English abstracts. This is convenient for collecting domestic research alongside foreign literature.
  • Sorting and filters
    By default, results are sorted by relevance (taking citations into account). Often, the first pages contain the most cited, "classic" works. You can switch to sorting by date to see the most recent publications. There is also a year filter to exclude outdated materials.
  • Useful features
    Below each result, there is an impact indicator showing "Cited by: X," where X is the number of works citing it in Scholar. There is a "Cite" button that generates references in different styles (APA, MLA, GOST, etc.). The "Related articles" link helps find similar works.

Keep in mind that Google Scholar finds everything, including sources of uneven quality (e.g., non-peer-reviewed materials, self-published works, student papers). You must critically evaluate sources: check where they were published (journal? conference? university?) and whether they are cited by others.
After an initial broad search via Scholar, it is advisable to turn to specialized databases that provide a more precise and vetted set of literature.
Tips for using Google Scholar:

    In eLibrary, you can search by fields: article title, author, keywords, abstract, organization (affiliation), and year of publication. For example, "digital diplomacy" AND year:[2015 TO 2025] AND (keywords:"foreign ministry" OR abstract:"social networks"). This query finds articles from 2015−2025 mentioning digital diplomacy and foreign ministries or social media. The interface allows such conditions to be set via search fields and filters.
  • Filtering
    Search results can easily be filtered:
    • by document type (journal article, conference proceedings, monograph, dissertation);
    • by journals (only those included in the Higher Attestation Commission list);
    • by full-text availability (PDF available);
    • by author or organization (e.g., MGIMO, St. Petersburg State University);
    • by year of publication and subject category ("Political Science and International Relations").
    For example, when preparing a dissertation literature review, it is better to select articles from accredited journals, while for a conference paper, abstracts and proceedings may also be suitable.
  • Results analysis
    eLibrary provides analytical data:
    • number of publications by year (dynamics charts);
    • citation counts for each publication;
    • author profiles with h-index and lists of other works.
    When studying digital diplomacy, you can see which Russian authors (e.g., N. A. Tsvetkova) publish and are cited most frequently in this field, which years were most productive, and which journals most often discuss the topic.
  • Citation analysis
    Each publication indicates the number of citations in RSCI. Clicking the citation count shows all works citing the publication. This helps quickly understand how the research develops and which authors actively cite each other. For example, a 2018 article on digital diplomacy may have 10 citations.

Scopus

Scopus is one of the largest databases of peer-reviewed literature (Elsevier). It requires a subscription (usually available through universities) but offers powerful search and analysis tools.
Features of working with Scopus
Features of working with Scopus
  • Advanced search
    You can search by various fields: title, abstract, keywords, author, affiliation, DOI, and combine conditions. For example: TITLE-ABS-KEY ("digital diplomacy") AND PUBYEAR > 2015 AND (LIMIT-TO (SUBJAREA, "SOCI") OR LIMIT-TO (SUBJAREA, "ARTS")) This query finds documents mentioning "digital diplomacy" after 2015 in social sciences and humanities.
  • Filtering
    Results can be filtered by year, document type (article, review, book chapter, etc.), subject area, country, and language. For example, you can select only reviews if you are looking specifically for literature reviews.
  • Results analysis
    Scopus has an Analyze Results function that generates charts:
    • distribution by year (showing publication peaks),
    • by authors,
    • by sources (journals),
    • by countries and institutions.
    For example, identifying top authors immediately highlights leading researchers (e.g., discovering that Ilan Manor is an author or co-author of many publications).
  • Citation analysis
    Each record shows the number of citations in Scopus and includes a View cited by button. This is analogous to "cited by" in Google but limited to high-quality materials indexed in Scopus. You can also click View references to see the bibliography used in an article, helping you quickly identify influential authors.
  • Export and collections
    You can select results (e.g., all 120 articles from a query) and export metadata (CSV, Excel, RIS for reference managers). This helps systematize sources and import dozens of entries into tools like Zotero at once.

Scopus is valuable because it primarily covers high-quality publications. It does not include unpublished dissertations or minor conferences (unlike Google). For international topics, Scopus finds most articles from leading English-language journals (Hague Journal of Diplomacy, Global Policy, Foreign Affairs, etc.), but contains little Russian-language literature.
After using Scopus, you will have a structured overview: key journals, main authors, and the most productive years. This forms the backbone of your bibliography.

/ WoS

Web of Science

Web of Science is another large academic database (Clarivate). In many respects, it duplicates Scopus: topic search, filters, analysis, citation metrics. Some journals are indexed only in WoS or only in Scopus, so it is sometimes worth checking both.
Features of working with Web of Science
  • Search
    Similar to Scopus, with combinations such as:
    TS=("digital diplomacy") AND PY=(2015−2025), where TS stands for topic (including title, abstract, keywords).
  • Citation network
    WoS allows you to view citations (Times Cited) and lists of citing works. There is also a Create Citation Report option that shows citation dynamics by year and the h-index for the results.
  • Web of Science categories
    Each journal is assigned to categories such as International Relations, Communication, Computer Science. You can filter by categories—digital diplomacy research typically falls under IR, Communication, and sometimes Public Administration.
  • Related databases
    WoS включает базы Science, Social Science, Arts & Humanities и региональные базы — в частности, RSCI (Индекс цитирования в российской науке) — подборку российских журналов на русском или английском. Можно переключиться на поиск внутри этой базы, чтобы выявить российские статьи по теме.
