What Is Digital Humanities?

Chapter 1: What Is Digital Humanities?

The Question That Started Everything

How many times have you searched for something online today? Maybe you looked up a historical event, read reviews of a movie, or searched for information about a famous person from the past. Now consider this: what if instead of searching for information one document at a time, you could analyze millions of documents simultaneously? What if a computer could help you discover patterns in history that humans alone could never see? This is exactly what Digital Humanities—the subject of this book—allows us to do.

For thousands of years, scholars studied history, literature, and art by reading individual texts carefully, one after another. A historian might spend an entire career reading letters, diaries, and official documents from a single decade. A literary critic might dedicate their life to understanding one author's works. This approach, called close reading, remains valuable. But what happens when you want to understand patterns across thousands of books, or trace how a single word's meaning has changed over two centuries? This is where Digital Humanities—often abbreviated as DH—changes everything.

Digital Humanities sits at the intersection of computing technology and traditional humanistic study. It combines the systematic power of computers with the interpretive depth of humanities disciplines like history, literature, art history, linguistics, and philosophy. DH scholars use computational tools to analyze vast collections of historical documents, literary texts, artworks, and cultural artifacts—patterns that would take humans lifetimes to discover become visible almost instantly. In this chapter, we will explore what Digital Humanities truly is, why it matters, and how you can begin using these powerful tools yourself.

The Collision of Two Worlds: Technology Meets the Humanities

Why Did Scholars Start Using Computers to Study Culture?

To understand Digital Humanities, we need to travel back to a specific moment in history. In 1949, a Jesuit priest named Roberto Busa contacted IBM founder Thomas Watson with a remarkable proposal. Busa wanted to create a computer-generated index of every word Thomas Aquinas ever wrote—not just in Latin, but across thousands of pages of commentary by other scholars about Aquinas's work. Watson reportedly asked Busa, "Do you think that mankind will really need this?" Busa responded, "Mankind needs it to understand thought."

This exchange marked one of the earliest attempts to use computers for humanistic scholarship. Busa's Index Thomisticus eventually took over three decades to complete and contained more than 11 million words. Today, it seems almost primitive compared to what Digital Humanities can accomplish, but Busa's vision—that computers could help us understand human thought in entirely new ways—remains the driving force behind the field.

The question is: why would scholars trained in reading and interpreting texts suddenly become interested in computing? The answer lies in the sheer volume of information available for study. Consider the British Library in London, which holds over 170 million items. The Library of Congress in Washington, D.C., contains approximately 38 million books. No human scholar could read even a small fraction of these materials in a single lifetime. Yet within these vast collections lie patterns waiting to be discovered—patterns that could reveal how language evolves, how cultures interact, and how societies change over time.

Digital Humanities emerged because scholars recognized that traditional methods, while valuable, had inherent limitations. Close reading excels at deep interpretation of individual texts, but it struggles to identify broader patterns across large collections. A literary critic reading fifty novels might miss a trend that becomes obvious when analyzing five thousand novels. Digital tools don't replace close reading; they complement it, allowing scholars to ask questions that were previously impossible to answer.

What Makes Digital Humanities Different from Traditional Humanities?

Traditional humanities scholarship emphasizes interpretation, context, and nuance. When a historian analyzes a single letter from the American Civil War, they consider the writer's background, the intended recipient, the historical moment, and the subtle meanings embedded in the language. This approach, sometimes called the hermeneutic tradition, treats each text as a unique artifact requiring careful, contextual interpretation.

Digital Humanities embraces these values while adding computational power to the scholar's toolkit. The key difference lies in scale and methodology. Where traditional approaches ask, "What does this particular text mean?" DH often asks, "What patterns emerge when we analyze thousands of texts together?"

Consider how these approaches might study the American Civil War. A traditional historian might carefully analyze Abraham Lincoln's Gettysburg Address, examining word choices, rhetorical structure, and historical context. A Digital Humanities scholar, meanwhile, might analyze all 25,000 letters in a digital archive of Civil War correspondence, using text mining software to identify which words soldiers used most frequently when writing home, how their language changed as the war progressed, or how their emotional expressions compared between Union and Confederate soldiers.

Neither approach is superior; they answer different questions. Traditional scholarship excels at deep, contextual understanding. Digital methods excel at revealing patterns invisible at smaller scales. The most exciting work in DH happens when scholars combine both approaches—using computational analysis to identify interesting patterns, then returning to close reading to interpret what those patterns mean.

Key Concepts That Changed Everything

Distant Reading: Seeing the Forest and the Trees

The term distant reading was coined by literary scholar Franco Moretti in 2000. Moretti argued that the traditional way of reading literature—individual texts, carefully analyzed—was like trying to understand an ecosystem by studying one square meter of forest floor. To truly understand literary history, he suggested, we need to step back and look at the entire landscape.

Distant reading doesn't mean reading less; it means reading differently. Instead of reading every novel in a century, a distant reader might use software to analyze plot structures across thousands of novels, identifying which narrative patterns dominated different decades. Instead of memorizing every word in Shakespeare's plays, a distant reader might trace how specific metaphors evolved across the entire canon.

Let us consider a concrete example. Suppose you wanted to understand how the English language changed during the Industrial Revolution (roughly 1750-1850). Using traditional methods, you might spend years reading representative texts from this period. With distant reading, you could use Google's Ngram Viewer—a free online tool that analyzes word frequencies in millions of books digitized by Google—to instantly see how specific words rose or fell in popularity across two centuries.

Imagine searching for the word "democracy" from 1750 to 1900. You might discover that the word barely appeared before 1780, then spiked dramatically around 1790 during the French Revolution, fluctuated through the early 1800s, and stabilized at much higher levels than before by the 1850s.
