Until the invention of the printing press, books were handwritten. This made books rare and very expensive.
Fabric designers in ancient times used carved woodblocks to decorate cloth and paper. In ninth century China, printers used the same method to print texts.
As Chinese writing uses characters, woodblock printing was efficient. But as European languages build words from single letters, woodblocks were great for printing pictures but not for text.
This changed when German inventor Johannes Gutenberg created type: small metal blocks, each with a single raised letter. Gutenberg arranged his type into rows, put them into woodblock printing presses, and printed pages.
Because type could be rearranged easily, and reused for many years, this form of printing was very efficient. In 1454, Gutenberg produced 180 copies of the Bible in just one year. It was a job that would take official copyists decades.
