Why Citations Matter in Research

This post is part of my Research Methods series , which explores essential approaches for historical inquiry and archival work. The series encompasses a broad range of topics, including library research practices, citations, and research strategies, as well as archives, primary sources, visual resources, oral history, and digital humanities. Together, these posts provide a foundation for navigating sources, interpreting evidence, and engaging critically with the past.

Citations are the scaffolding of scholarship. They connect one piece of research to another, forming a chain of evidence that allows others to verify, question, or expand upon what has been written. For historians in particular, citations are more than technical formalities; they are acts of intellectual honesty, signposts for future researchers, and opportunities to amplify voices that might otherwise remain unheard.

While the mechanics of citation may appear daunting at first, especially with the detailed requirements of styles like Chicago or Turabian, the underlying principle is simple: show readers where your ideas and evidence come from, and do so in a way that fosters clarity and trust.

Why Chicago/Turabian Is the Standard

In history writing, the Chicago Manual of Style and its student-friendly counterpart, Kate Turabian’s A Manual for Writers of Research Papers, Theses, and Dissertations, remain the gold standards. These guides prioritize flexibility, which is crucial for historians who work with sources ranging from archival manuscripts to oral histories, digital databases, and even social media content, such as memes.

Unlike parenthetical systems such as APA or MLA, which place citations in parentheses within the text, Chicago’s Notes and Bibliography style allows for footnotes or endnotes that accommodate lengthy explanations, archival details, and layered commentary. This method not only supports accuracy but also mirrors the historian’s work itself: contextual, nuanced, and deeply engaged with sources.

The Stakes of Citation

Why labor over punctuation, page numbers, and formats? Because citations matter in ways that extend beyond mechanics:

They signal significance. Citations demonstrate that research is built on a foundation of evidence. They answer the implicit “So what?” by showing how data connects to broader conversations.

They guard against sloppiness. Inconsistent or incomplete citations cast doubt on the rigor of the entire project. Sloppy notes imply sloppy thinking.

They guide future researchers. Every reference is a breadcrumb that may help another scholar locate and build upon your work.

For historians, who often deal with rare or obscure sources, impeccable citations ensure that materials can be traced, revisited, and reinterpreted over time.

What to Cite and What Not To

Historians must cite more than direct quotations. Paraphrases, summaries, and borrowed ideas that are not common knowledge all require acknowledgment. If a reader could reasonably assume the information came from you, but in fact it was drawn from elsewhere, a citation is needed.

The guiding principle is transparency. If in doubt, cite. If you cannot access the original source and must rely on a secondary reference, make that clear in your note. This avoids misleading readers into thinking you worked directly with a source that you did not.

Footnotes, Endnotes, and the Reader’s Experience

Citations can appear as footnotes at the bottom of the page or as endnotes at the back of a chapter or book. Each method has advantages:

Footnotes enable readers to view references immediately, making them accessible yet potentially distracting.

Endnotes keep the page cleaner but force readers to flip back and forth.

For books and journals, endnotes are often preferred, while in shorter works, footnotes remain common. Both methods enable historians to include not only citations but also explanatory notes, providing context or clarifying interpretations.

Quoting with Care

Quotations clarify, enrich, and support arguments, but they must be used sparingly. Whenever possible, summarizing or paraphrasing an author’s argument while still citing the source strengthens analysis. Direct quotations are most powerful when interpreting primary sources or when an author’s phrasing itself is crucial.

Historians also follow conventions for formatting quotations. Short quotations run within the text, while longer ones become block quotations, indented and set apart without quotation marks. Contextual introductions help the quotation flow within the narrative, while brackets and ellipses should be used with restraint to preserve clarity.

Handling Repeated Sources

When citing the same source multiple times, historians traditionally relied on the abbreviation “Ibid.” (from the Latin ibidem, meaning “in the same place”). Today, many scholars prefer shortened citations (e.g., “Salmond, 300”) for clarity.

Regardless of preference, consistency is key. Drafting with full citations first and shortening later prevents confusion during revisions.

Dates, Tenses, and Historical Writing

Citations also raise subtle questions of dates and tenses. Publication dates matter because they situate scholarship within its intellectual moment. Historians often compare works across decades to trace the evolution of interpretations.

Verb tense also carries meaning:

Past tense for historical events (“de Beauvoir published The Second Sex in 1949”).

Present tense for the content of documents or ongoing scholarly arguments (“In the book, she contends that women…”).

This balance between past and present highlights the dual task of historians: narrating events while analyzing the conversations around them.

Navigating Digital Sources

The digital landscape has complicated citation practices, but principles remain the same: be precise, consistent, and helpful to future readers.

Online articles should include a DOI (Digital Object Identifier) whenever possible, as DOIs provide permanent links. If unavailable, URLs may be used, along with an access date.

Websites and blogs require as much detail as possible, including author, title, publication date, and access date. URLs alone are never enough.

Social media can be cited, but it is wise to capture screenshots for personal records, as posts may disappear over time.

By treating digital sources with the same rigor as print, historians safeguard the reliability of their work.

Inclusive Citations

Citations are not neutral. Choosing whom to cite shapes the intellectual community a work engages with and perpetuates. Inclusive citation practices ask researchers to consider:

Whose voices are being amplified?

Which perspectives are missing?

How might broadening citations strengthen the depth and relevance of the work?

In this way, citations become tools of justice as well as scholarship.

Beyond Books: Special Cases

Historians cite a vast range of materials:

Archival materials often come with prescribed citation formats provided by the archives itself.

Legal cases follow strict conventions, usually limited to notes.

Images and audiovisual sources may be cited in captions or notes, with special attention to permissions if publishing.

Oral histories and personal communication typically appear in notes or within the text, rather than in bibliographies.

Each type of source requires sensitivity to its context, audience, and accessibility.

Avoiding Plagiarism

Perhaps the most practical reason for rigorous citation is avoiding plagiarism. Plagiarism can be intentional, but often it happens inadvertently through sloppy note-taking, overreliance on paraphrasing, or failure to distinguish one’s ideas from another’s. Careful citation practices prevent these pitfalls, ensuring that credit is given where due and protecting the integrity of scholarship.

The Ongoing Practice of Citation

Citations are less about adhering to formatting rules and more about upholding intellectual ethics. They ensure transparency, foster trust, and knit research into broader scholarly conversations. For historians, citations also embody humility: an acknowledgment that every interpretation stands on the work of others.

As digital resources proliferate and research becomes increasingly interdisciplinary, the need for clarity, accuracy, and inclusivity in citation will continue to grow. By approaching citations with care, historians not only strengthen their own work but also leave a clear trail for those who follow.

Citations are the unsung heroes of history writing. They demand time and attention, but they reward scholars with credibility, connection, and contribution. Whether citing a centuries-old manuscript, a peer-reviewed article, or a fleeting social media post, the principle remains the same: respect your sources and your readers.

Meticulous citations remind us that history is never written in isolation. Each note, each reference, and each acknowledgment ties one researcher’s work into a living web of scholarship: a web that will continue to grow as others build on what has been carefully documented today.
