Printing did not begin with Gutenberg. Texts made from woodblocks appeared in China centuries earlier, and the technology spread across East Asia. Printed works survive from eighth-century Japan, and metal movable type was used in Korea before Gutenberg’s time. The change in fifteenth-century Europe belongs within this longer global history.
In Europe then, many books were still copied by hand. They required skilled writers, animal skin or paper, ink, and long hours of work. Pages could also be printed from carved wooden blocks, but each full page needed its own block. Producing many matching copies of a long text was therefore difficult.
Johannes Gutenberg combined a mechanical press with a method for making uniform, interchangeable metal type. After printing one sheet, workers could rearrange the pieces for another page instead of carving or writing the whole text again. His Bible, completed in Mainz around 1455, became a major turning point in Western European bookmaking.
The change was not immediate. Early printed books could remain expensive, and color or decoration was sometimes added by hand. Manuscripts and printed books existed together for a long time. Rather than making every book immediately cheap, its central strength was the ability to reproduce a text in multiple copies from the same setting of type.
This multiplication changed reading. As texts circulated more widely, readers in distant places had more opportunities to encounter the same words. Scholars could compare texts, students could refer to shared editions, and debates could begin from the same reference point. If an edition contained an error, many copies could spread it, yet readers could also identify the same passage, compare versions, and correct it in a later edition.
Printing did not spread only truth. It could multiply rumors, attacks, and false claims along with reliable scholarship. Printing did not create literacy or social change by itself. Education, paper, trade, and distribution networks also mattered. Even so, print made texts repeatedly shareable among larger groups and connected reading to a wider public conversation.
