How do researchers uncover histories that were intentionally hidden, forgotten, overlooked, or perhaps never asked? Or maybe the right question is whether a particular topic has been overlooked, or whether someone failed to ask it? Research is not simply gathering facts. It is the process of finding fragments of evidence and weaving them into meaningful narratives that help us better understand the past. It’s a form of storytelling. What story needs to be shared? Like storytellers, investigative researchers construct narratives; their stories are grounded in evidence from primary sources and shaped by analysis, not imagination. When students conduct investigative research, they do more than collect sources. They become storytellers who transform documents, interviews, and archival records into narratives or write hidden stories.

Wars and reforms are not the only reasons history is missing. Marginalized groups have often been excluded from official archives, while governments, organizations, and individuals sometimes keep information secret. For example, the British government and MI6 have not released all records of their covert operations and propaganda efforts in the United States during World War II. Although the countries were allies, the United Kingdom needed the United States to be fully invested in the war. This is where the British Security Coordination (BSC) stepped in, stationing several spies in Washington, DC, and New York. Why haven’t all the documents been released? What secrets could still be hidden? Is there more to the story? Were any of these spies women? Women’s contributions to scientific discoveries and war efforts remain hidden today, just as Indigenous voices are often missing from historical records because of a reliance on oral histories and deliberate efforts to silence communities. Examples like these remind us that research begins not only with what we can find, but also with what might be missing.
How, then, do researchers investigate those gaps? Start by asking what has not been considered. Look at who wrote the existing histories, when they wrote them, and whose perspectives they included. Then ask those questions again. This process is like plotting a story or essay: it is the background work that shapes everything that follows. Historical research often requires asking questions repeatedly because sometimes the answers are available and other times they are not. Once you have identified the gaps, begin looking for and following the evidence. Track clues across multiple sources and archives rather than relying on a single collection. Researchers rarely begin with complete information, so investigative research requires patience and flexibility. Good researchers do not have all the answers; they know how to ask better questions.
Good researchers must also understand the tools that drive discovery and storytelling. Primary sources—such as letters, diaries, interviews, government records, newspapers, and photographs—provide firsthand evidence. Sometimes these materials are easy to access; other times, you may need to travel. Archives and special collections, along with their staff, can be invaluable, but a library database is often a good place to start. Newspaper databases also contain a wealth of information. Does your story need oral history? Can you interview people or read existing interviews? Could a personal narrative add another perspective? Consider sources that preserve experiences often absent from written records. Government document repositories, census records, and digital humanities projects may also provide essential evidence.
Once you have gathered your evidence—the “bones” of your story—what conclusions can you draw? How do the sources fit within their larger historical context? Every claim must be supported by evidence, and every story must be told with integrity. Although the historical record may contain gaps, researchers must represent people and places ethically. History is not about uncovering a secret to reveal it; it is about deepening our understanding through evidence-based storytelling. At this stage, you apply the critical-thinking, communication, and source-evaluation skills your English and history teachers emphasized. You also consider whose voices are included and whose are still missing. In doing so, investigative research can help students become stronger scholars and more thoughtful participants in public conversations.
The most fascinating stories are not always the easiest to find. Sometimes they are waiting in an archive box, an overlooked interview, or a forgotten document for someone curious enough to ask the next question. For me, that curiosity extends to old botanical books, manuscripts, and illustrations. Scholars have written extensively about these books, but what might their margins reveal? Although this subject is outside my field, the question illustrates the heart of investigative research: even a familiar object can tell a new story when someone looks beyond its pages and asks what others may have overlooked.
