== =Printing Press= In 1440, German inventor Johannes Gutenberg invented a printing press process that, with refinements and increased mechanization, remained the principal means of printing until the late 20th century. The inventor's method of printing from movable type, including the use of metal molds and alloys, a special press, and oil-based inks, allowed for the first time the mass production of printed books. The printing press led to;
 * the mass production of books, specifically the Bible
 * cut the cost of books
 * more people learned to read
 * more people learned indulgences were bad by reading the Bible
 * a revolt against the Catholic Church began

Printing stimulated the literacy of lay people and eventually came to have a deep and lasting impact on their private lives. Although most of the earliest books dealt with religious subjects, students, businessmen, and upper and middle class people bought books on all subjects. Printers responded with moralizing, medical, practical and travel manuals. Printing provided a superior basis for scholarship and prevented the further corruption of texts through hand copying. By giving all scholars the same text to work from, it made progress in critical scholarship and science faster and more reliable. Learn more at: []
