The ancient Greeks wrote texts intended for education. The modern textbook has its roots in the standardization made possible by the printing press. Johannes Gutenberg himself may have printed editions of Ars Minor, a schoolbook on Latin grammar by Aelius Donatus. Early textbooks were used by tutors and teachers, who used the books as instructional aids (e.g., alphabet books), as well as individuals who taught themselves.

(Paradoxically, we know about Socrates' concerns only because they were written down by his student Plato in his famous Dialogues.)The next revolution for books came with the 15th-century invention of printing with changeable type. The invention is attributed to German metalsmith Johannes Gutenberg, who cast type in molds using a melted metal alloy and constructed a wooden-screw printing press to transfer the image onto paper.
