The definition of 'book' has evolved dramatically in our digital era. This course explores books through four essential perspectives: their physical form (materials, structure), their content (how they are written, read, collected, and sometimes banned), their technology (from Gutenberg's printing press to today's e-readers), and their artistic value. By studying how information sharing has transformed over centuries, participants will gain insight into the enduring impact of books on culture, literacy, and society.
