Seven Days in Cheongju: A Kentucky Teacher's Pilgrimage to the Book That Changed Her Classroom

I have taught world history in a Kentucky public high school for eleven years. For ten of them, I taught the invention of printing the way my own teachers had: Gutenberg, Mainz, 1455, the flood of books that followed. Then a colleague forwarded me an article about a Korean Buddhist text called Jikji, printed with movable metal type seventy-eight years before the Gutenberg Bible.

I remember sitting in the school parking lot after reading it, embarrassed. Not because I had been negligent—because no one had ever told me. I decided my students would not graduate with the same gap in their understanding. What followed was a semester of rebuilding my printing unit, and, eventually, a decision that surprised even me: I needed to see the book's home with my own eyes.

Crowdfunding a Pilgrimage

I am not a wealthy traveler. My district does not fund professional development abroad. So I did what teachers do: I asked. A small online campaign—shared by former students, parents, and strangers interested in printing history—covered airfare and lodging for a week in South Korea, timed to a period when the Cheongju Early Printing Museum offers extended public programming.

What the Museum Gave Me That No Facsimile Could

Standing in Cheongju, I understood something I could only gesture at in class. The museum sits amid reconstructed workshops where artisans cast type, prepare ink, and pull sheets on hanji paper. The demonstration is not theater; it is reconstruction, grounded in the evidence of Jikji itself.

Three things stayed with me:

1. The paper. Hanji is nothing like European rag paper. Seeing sheets of it, feeling its strength, explained in seconds why Korean printing developed as it did.
2. The scale of the type. Photographs flatten everything. In person, the reproduction casts convey how much labor a single page demanded.
3. The pride of place. Cheongju treats Jikji not as a trophy but as a responsibility. That framing shaped how I now teach cultural heritage to my students.

Bringing Cheongju Back to Kentucky

I flew home with photographs, museum publications, and a rubbing of a hangul block made during a workshop. But the most useful souvenirs were free: the museum's digital resources, many of which any American teacher can access without a passport.

For educators who cannot make the trip, the path is shorter than you think. High-resolution facsimiles of Jikji's surviving volumes are available online. The Jikji Museum offers classroom-ready materials on the history of movable type in Korea. And a single lesson comparing Jikji (1377) with the Gutenberg Bible (1455) will change how your students understand the word "invention."

I teach the story differently now. I no longer say printing was invented in one place at one time. I say: humans in more than one civilization solved this problem brilliantly—and one of the finest answers we still hold came from Cheongju, in 1377, in a book called Jikji.
