Types of Historical Research: Exploring Different Approaches

Step into any history department and you’ll quickly notice that historians rarely agree on a single way to study the past. Some pore over the diaries of a single individual, while others trace the rise and fall of entire institutions. A few prefer to follow a theme across centuries, and still others argue endlessly about the right method to use at all. This variety is not a weakness; it is the strength of historical research. Each approach acts like a different lens, revealing details that another might miss. In this post, we’ll break down the major types of historical research, from biographical and institutional studies to thematic approaches and the methodological schools that shape how historians work.

Why historical research has many forms 🔗

Historical research is the systematic study of past events using surviving evidence. But the past is vast, and no single method can capture all of it. A historian studying the freedom struggle will need different tools than one studying the evolution of a university library. The historical method begins with defining the problem, locating sources, and critically evaluating them before any narrative is written. How a researcher frames that problem largely determines which type of research they end up doing.

For students of Library and Information Science, these approaches are not just academic. They help explain how libraries, archives, and information systems developed over time, and why current debates about access, censorship, and digitisation have deep historical roots. Understanding the different types of research equips you to ask sharper questions and select the right evidence.

Biographical research: history through individual lives 🔗

Biographical research studies the past by focusing on the life of a single person. This could be a national leader, a reformer, a scientist, or, in the LIS context, a pioneering librarian such as S. R. Ranganathan. By zooming in on one life, historians can examine specific moments in great detail, capturing decisions and motivations that broader narratives often overlook.

Biographical research isn’t limited to famous figures. It can also illuminate the lives of ordinary or lesser-known people, adding richness to our understanding of an era. That said, the genre has its critics. Some historians argue that the surviving written record is heavily biased toward extraordinary individuals, making biographies of common people difficult to write. The approach has nonetheless evolved considerably, moving from early hagiographic or heroic accounts toward more nuanced work that situates a person within their social, psychological, and political context.

Tools of the biographer 🔗

A biographer typically works with letters, diaries, personal papers, interviews, and official records. The challenge is balance: telling a coherent story without oversimplifying a complex human being. Increasingly, historians draw on theoretical frameworks, including feminist, postcolonial, and Marxist perspectives, to interpret a subject’s experiences and avoid a flat, one-dimensional portrait.

Institutional research: tracing organisations over time 🔗

Institutional research shifts the focus from individuals to organisations. Institutions, whether educational, religious, political, or economic, form the backbone of any society. Studying how they emerge, grow, and sometimes decline reveals a great deal about how communities functioned and changed. A researcher might examine the development of the university system, the rise of democratic bodies, or the formation of a public library network.

Within LIS, institutional histories are especially valuable. Tracing the growth of a library or documentation centre shows how information storage and retrieval practices adapted to changing societal needs, from ancient collections to modern digital archives. This kind of work helps explain, for instance, the role of libraries during the colonial period and how they preserved local knowledge.

Sources behind institutional histories 🔗

Institutional research relies heavily on records generated by the organisation itself. These include minutes of meetings, annual reports, administrative correspondence, policy documents, and registers. Such sources offer a window into both the machinery of the institution and the people who ran it. By following these documents over decades, historians can trace how laws, traditions, and norms took shape, many of which still influence society today.

Investigation of sources: the foundation of all historical research 🔗

No matter which type of research you pursue, everything rests on the quality of your sources. Historians divide evidence into two broad categories. Primary sources are directly connected to the event being studied, such as eyewitness accounts, government records, letters, and artefacts. Secondary sources are produced later and based on primary material, including textbooks, biographies, and encyclopaedias. Because information can be distorted as it passes from one secondary work to another, researchers are advised to rely on primary sources wherever possible.

External and internal criticism 🔗

Once sources are gathered, they must be tested. This evaluation, known as source criticism, has two levels. External criticism, sometimes called lower criticism or heuristics, establishes whether a document is authentic by examining its date, place of origin, authorship, and physical characteristics like paper and ink. Its function is largely negative: it saves the researcher from using false evidence.

Internal criticism, or higher criticism, goes deeper. It assesses the credibility and trustworthiness of the content, asking whether the author was honest, well-informed, and free of bias. A document can be perfectly genuine yet still contain unreliable claims, which is why both forms of criticism are essential. Together they help the historian arrive at a dependable account of the past before moving on to interpretation.

Thematic research: studying history through ideas and influences 🔗

Some historians prefer a wider angle. Thematic research organises the past around a central theme, such as religion, gender, economics, caste, or culture, and then analyses how that theme shaped events across time. Instead of following one life or one institution, the researcher follows an idea.

The great strength of this approach is its ability to connect seemingly unrelated events across different periods and regions. A study of education as a theme, for example, might link ancient learning centres, colonial schooling policies, and modern literacy campaigns into a single coherent story. Thematic work often overlaps with intellectual history, which studies the development and influence of ideas, and with political history, which analyses the evolution of political systems and ideologies.

Bibliography and the history of the book 🔗

A theme particularly close to LIS is the history of the book and bibliography. Researchers in this area study how texts were produced, circulated, catalogued, and preserved. This connects historical research directly to core library concerns, including documentation, classification, and the transmission of knowledge across generations. Tracing how a particular text or genre spread can reveal much about literacy, technology, and cultural exchange.

Methodological variations: schools of thought 🔗

Beyond the subject of study, historians differ in the very methods they adopt. These choices usually reflect a school of thought, a broader philosophy about what history is and how it should be written. Three approaches are especially important for students to know.

Narrative history 🔗

The traditional approach is narrative history, which tells the story of the past in a chronological and descriptive manner. Historians working in this mode tend to emphasise political events, wars, and influential figures, weaving them into a connected story. The aim is coherence: presenting history as a sequence of interrelated events that a reader can follow from beginning to end.

New social history 🔗

New social history emerged as a powerful alternative in the mid-twentieth century. Often described as history from below, it shifted attention away from kings and statesmen toward ordinary people, including workers, peasants, women, and marginalised communities. Influenced by the French Annales School and the work of historians like E. P. Thompson, this approach replaced the top-down model with a bottom-up one, exploring family, community, and everyday life. For archivists and librarians, this shift mattered too, as it broadened the kinds of records considered worth preserving.

Quantitative and other approaches 🔗

A further variation is quantitative history, which uses statistical data, such as census records, price lists, and demographic figures, to identify patterns over time. More recently, the growth of digital tools has enabled data-driven and computational approaches, alongside a renewed emphasis on global and cultural perspectives that challenge Eurocentric narratives. These schools are not mutually exclusive; many historians blend several to suit their question.

How to choose the right approach 🔗

So which type should a researcher use? The honest answer is that it depends on the question, the available sources, and the researcher’s own interests. A scholar curious about one reformer’s impact will lean toward biography. Someone studying a library’s evolution will choose institutional history. A researcher tracing the idea of freedom across decades will adopt a thematic approach. Often, the strongest research combines methods, using a biographical lens within an institutional study, or quantitative data to support a social history argument.

What unites all these approaches is rigour. Whatever path you take, the discipline demands careful source investigation, honest criticism, and a willingness to revise conclusions when the evidence points elsewhere. That shared commitment to evidence is what makes history a genuine field of research rather than mere storytelling.

What do you think? If you were to research the history of your own college library, which approach would you choose first, and why? And do you believe the rise of digital tools and computational methods will eventually overtake the traditional narrative style of writing history?
